Frequently asked questions

ippi uses an open, open-source protocol based on SIP technology. This is not the case for some competitors, who use a closed proprietary protocol or who use your bandwidth as a relay point on their network, even when you are not using the telephony service.

The advantages may depend on several factors, such as:

• the compatibility of your phone equipment, very often SIP-compatible;

• your country of residence;

• cheaper rates and plans, better suited to your needs;

• innovative services;

• a no-commitment offer, like the one ippi provides.

Discover our offers: free SIP account, SIP trunk and cloud phone system.

You can order one in the country of your choice, on its own or with an unlimited plan (special offer). Depending on the country, local regulations may require a proof of residence.

The ippi service can be used worldwide with a fixed or mobile broadband internet connection. Some countries may however block VoIP. It is nevertheless possible to bypass this block with a VPN tunnel. Please check the regulations in force in your country.

No, not beyond one month.

You can enter the fixed-line number of your choice (mobile numbers are not accepted) on the configuration page of your dashboard.

If your application, software, adapter, phone or IPBX is SIP compatible, it should work with ippi.

ippi is a partner of most developers and manufacturers, and has received numerous certifications.

Default settings:

A SIP account is a phone line over the Internet. It works with any SIP-compatible device:

• Softphone: on a computer or mobile

• IP phone: a desk phone

• Adapter or router: to connect a regular phone

With ippi it is free and lets you call and be called wherever you have an Internet connection.

Yes. The account is free with no contract, and calls between ippi users and to open SIP networks are free. You only pay for what you add:

• A number: to be called from landlines and mobiles: €3 excl. VAT per month for a French number, €5 or €10 for other countries, plus the inbound line at €5 excl. VAT per month

• An extra inbound line: €5 excl. VAT per month to receive one more call at the same time

• Credit: to call landlines and mobiles, billed per second (see the out-of-plan rates by destination)

A few minutes:

• Sign up: choose a username, enter your email address and a password, then accept the terms

• SIP credentials: find them in your account

• Setup: enter them in your device, and you are ready

Three different uses:

• SIP account or SIP line: for one user and their devices; both terms mean the same thing

• SIP trunk: to connect a business phone system (IP PBX) to the phone network, with several simultaneous calls: see the SIP trunk

• Cloud phone system: for a whole team without hardware: see the cloud phone system

Yes, on all your devices:

• iPhone: with the ippi Softphone app or any other SIP-compatible app

• Android and computer: with any SIP softphone

• IP phones, adapters and routers: SIP-compatible

Up to 3 devices can be connected at the same time.

Yes. Your SIP account works wherever you have Internet access: you receive calls on your number and call at ippi rates, wherever you are.

The SIP account that comes with an Internet subscription usually only works with that provider’s router, at home. The ippi SIP account is independent of your Internet provider:

• Anywhere: it works on all your SIP devices, wherever you are

• For good: you keep it if you change router or provider

ippi sells outbound and inbound channels separately:

• Elite plan: 1 outbound channel (unlimited calls), 1 inbound channel and 1 number

• Inbound line: 1 more inbound channel, without a plan

Plan as many plans as simultaneous outbound calls (usually one for three to four phones), then inbound lines if you receive more calls at the same time, for example for a busy front desk. You adjust any time, no contract.

• Elite plan (€19.99 excl. VAT/month): 1 unlimited outbound call, 1 inbound call and 1 number

• Inbound line (€5 excl. VAT/month): only the ability to receive one more call at the same time

Yes. The ippi SIP trunk works with SIP-compatible IP PBXs: Yeastar, Asterisk and FreePBX, 3CX, Wazo, Innovaphone, Tiptel, Epygi… Step-by-step setups are in the FAQ.

Calls to landlines and mobiles in 150 destinations, under fair use:

• Numbers: calls included to 100 different numbers per month

• Duration: the first 60 minutes of each call are included

Yes, at any time and with no commitment, from your customer account: add a plan, an inbound line or a number. Your IP PBX configuration does not change.

Yes:

• Create a free SIP account: in a few minutes

• Connect it to your IP PBX: to check the setup and call quality between SIP users

• Switch to the unlimited plan: when everything is ready

• You already have an IP phone system: on site or hosted: the SIP trunk connects it to the phone network and you keep its configuration

• You have no phone system: or no longer want to manage one: the ippi Centrex cloud phone system provides greeting, IVR menu, call queues and business hours, with no hardware, from €8.33 excl. VAT per user

It is a phone system hosted in the cloud by ippi, instead of a box installed on your premises. You set it up from your online account:

• Greeting: welcome message and hold music

• Routing: IVR menu, call queues, business hours

• Voicemail: voice messages sent by email

Your team answers on an IP phone, on their computer or in the browser with the included webphone.

To see what it looks like, browse our 4 phone system examples, from simplest to most advanced.

• PBX: a physical phone system installed on site, which you buy, maintain and connect to phone lines

• IP PBX: the same over the Internet, but often still equipment to manage

• ippi Centrex: the phone system is hosted and updated by ippi: a monthly subscription, nothing to install

Already have an IP PBX? The ippi SIP trunk connects it to the phone network.

With ippi Centrex, 2 plans cover up to 6 users for €49.98 excl. VAT per month, i.e. €8.33 excl. VAT per user. They include:

• Numbers: 2 numbers

• Simultaneous calls: 2 outbound and 2 inbound calls

• Setup: €10 excl. VAT, no contract

No. Each user can make and answer calls from the browser with the included webphone. They can also keep the SIP software or hardware they are used to:

• Softphone: on their computer or mobile

• IP phone: a desk phone (Yealink, Grandstream, Snom, Gigaset…)

An ippi Centrex mobile app is in preparation.

Yes. The phone system is online: a team member answers from home just like in the office, with:

• The webphone: in their browser

• A SIP softphone: on their computer or mobile

The IVR menu can also forward a call to an external number, such as a mobile.

Yes, in countries where number porting is available: your number is transferred to ippi and keeps ringing on your phone system. The list of countries is shown in the “Included in every plan” section.

ippi sells outbound and inbound channels separately:

• Each plan: 1 outbound and 1 inbound simultaneous call, for 3 users

• More incoming calls: add inbound lines at €5 excl. VAT per month

• More users: add a plan: 3 more users

Yes. Each plan covers 3 users: simply add a plan from your customer account, with no commitment.

No. ippi Centrex has no contract: you can cancel at any time, effective at the end of the current month.

The VAT rate applied is the French rate, i.e. 20% for individuals and businesses residing in France, as well as for individuals residing in the European Union. VAT is not applied to businesses in the European Union that provide their intra-Community VAT number, nor to foreign residents who provide proof of address.

Monthly billing is done at the beginning of each month.

If your account is in prepaid mode, the accepted payment methods are:

• Visa

• Mastercard

• PayPal

If your account is in postpaid mode, the accepted payment methods are:

• Visa

• Mastercard

• Bank account (European Union only)

If there is a rejection, you are notified by e-mail, and a flat fee of 15 euros is charged to cover our bank and management fees.

Subscriptions are billed in advance, at the beginning of each month. If a subscription is taken out during the month, an invoice is issued the same day, based on one full month of subscription. When the next monthly invoice is issued, one month of subscription is again billed in advance, less a pro-rata deduction for the period of the previous month during which the subscription was not yet active.

Cancellation takes effect at the end of the current month. Your subscription therefore remains active until that date.

The request must be made from your dashboard.

The password can be changed from the dedicated page in your dashboard.

This can be due to your balance still being above €3 (excl. tax), to you having reached the maximum number of top-ups allowed within a given period, or to a protection mechanism preventing the top-up. For more information, please contact support.

No. If you really want a different username, we invite you to open a new account and let us know.

Your details can be changed on your dashboard.

Your payment methods can be changed on your dashboard.

You can top up your prepaid account by credit card or PayPal, directly from your dashboard.

A prepaid top-up is valid for 365 days. This period is extended by another 365 days each time a new top-up is made before it expires.

Remember to top up your account before the end of this period to keep it valid.

Your subscription can be changed from your dashboard.

Please see the list of rates per destination on the main page of the site.

The rate is the same as for calls. You will find the list of rates per destination on the main page of the site.

The RIO (Relevé d’Identité Opérateur) is a code required to transfer your French phone number to another provider while keeping the same number.

To obtain your RIO from ippi, please contact our support team and provide the phone number concerned. We will assist you in retrieving your RIO code.

Yes, and there is no limit. You can have one or more numbers on the same account: in that case, all calls to these numbers ring on the account, unless it is configured on an IP PBX (phone system), where calls can be redirected to the right extension.

You can also have several numbers spread across several accounts: in that case, calls to a number ring only on the matching account. It depends on your needs.

No.

No, you can receive calls on your SIP address or number (user@sip.ippi.com) from other ippi users or from third-party SIP networks.

It's the rate of a local or national call if the caller is in the same country as the number, or an international rate if the caller is in another country. For more information, please contact your telecom provider to find out the rate for calls to that number's destination.

No, it is not necessary to have a virtual number to make calls.

Would you like to keep your current phone number when switching to ippi? You can do so through number portability. ippi supports number portability in many countries.

1. Obtain your RIO code from your current provider.

2. Log in to your personal account and go to the “Number” menu. Click “Add number +”, then “Add +”. From the dropdown menu, select “Fixed line to port” and choose the relevant country. Then enter the name of your current provider, the phone number you wish to port, and your RIO code.

3. Submit your request. ippi will guide you through the process until your number porting is confirmed.

Porting times and requirements depend on the country, the type of number, and the provider involved.

Important: do not cancel your existing phone line with your current provider before the porting process is completed. Porting generally results in the cancellation of services associated with the transferred number, subject to the applicable terms and conditions.

If you have any questions, please contact our team via the Contact page.

No.

The virtual number can be changed by contacting support. This service is charged 5 euros.

You probably no longer have a subscription, and the number was terminated automatically. It is not normally possible to retrieve a lost number. A new number will be assigned if you take out a new subscription.

Calls are free between ippi users and to open SIP networks.

The SIP number is used to receive calls from other users, only on the ippi network. This number is easier to dial than a SIP address with letters (user@sip.ippi.com).

It comes with every ippi SIP account, even a free one.

If you do not have a virtual number, and you have not activated caller ID privacy, our main server's number, +33 1 76 600 700, is displayed by default.

You can dial *1400 to run an echo test.

A SIP trunk (SIP trunking) lets you make and receive phone calls over the Internet, without a traditional phone line. It uses the SIP protocol to connect your phone system to the telephone network.

Discover the ippi SIP trunk: unlimited calls to 150 destinations, number included.

A SIP trunk is cheaper, more flexible and easier to set up than traditional telephony.

Prices and compatibility: see our SIP trunk offer.

A fixed or mobile broadband Internet connection, and a SIP-compatible application, software, phone or telecom system.

To get started, create a free SIP account.

It depends on your plan:

• With the free (prepaid) account, you can make one call at a time. One inbound channel is included for SIP calls (ippi users and SIP addresses). To receive calls on a number, add at least one inbound line.

• With unlimited plans, each plan adds one simultaneous outbound and one inbound call. For example, with 3 plans you can make 3 calls and receive 3 at the same time.

To make more calls at the same time, add a plan. To receive more, add inbound lines from your dashboard, without taking another plan: with 2 plans and 3 inbound lines, you can make 2 calls and receive 5 at the same time. There is no limit on the number of inbound lines.

For an IP PBX, see the SIP trunk; for a team without hardware, the cloud phone system.

ippi offers HD (High Definition) sound quality for your calls thanks to the G722 codec, between two users with compatible hardware. ippi also offers premium quality on all fixed and mobile destinations thanks to the G711 and G729 codecs.

ippi uses the open SIP protocol.

The supported codecs are: G711, G729 and GSM, plus HD sound in G722 between compatible devices.

Each ippi account can have 3 simultaneous SIP connections. This allows you to permanently connect an IP phone or PBX, a softphone, and an application. This number cannot be changed.

This can have two main causes:

• you may not be connected to the ippi network. You can check this in the SIP Connections section of your dashboard;

• you are connected, but your Internet network is blocking the SIP protocol, either because your ISP uses the same UDP port 5060 for its own telephony service, or because your router blocks this port by default for security reasons.

In the first case, use our alternative UDP port 34550 (Proxy: sip.ippi.com:34550). In the second case, permanently open UDP port 5060 in your Internet box or router configuration.

• You probably don't have enough credit or a subscription on your ippi account to call paid numbers.

• A security measure may have been activated on your account: in this case, please contact our support team.

1. Check in your dashboard that you are connected to the ippi network.

2. Check that you have validated your account by clicking the link sent by email when you registered.

If you still can't get through, please contact our support team.

Your phone, software, or app is not sending a DTMF (Dual-Tone Multi-Frequency) signal, so our server cannot understand your instructions.

In this case, enable the DTMF via SIP INFO setting in your device or application configuration.

Check the following:

• the call forwarding option has been activated;

• the forwarding number is correct;

• your balance is positive, if you have a prepaid account without a subscription.

1. Check that the dialed number is correct.

2. Test it from a line other than ippi.

3. If you still can't reach it, contact our support team, mentioning the number along with the date and time of the call.

1. Check your Internet access.

2. Check the connections of your setup, or close and restart your SIP client (software, application, IP PBX…).

If the problem persists, please contact support.

This is very often due to low bandwidth, i.e. an Internet speed that isn't high enough to carry voice traffic. Several solutions can help:

• use a more powerful Internet connection;

• choose a less demanding codec that compresses voice better, such as G729 instead of G711.

Sometimes the bandwidth is sufficient, but the local configuration of the Internet access degrades voice quality. In this case, check your configuration and allocate a channel dedicated to VoIP (MPLS).

One-way sound usually indicates a problem with the router (NAT). If your router is blocking the sound, you can:

• enable or disable STUN on your SIP client (stun.ippi.com);

• change the registration time (REGISTER) of your SIP client to 120 seconds.

The ippi Softphone app is currently available on iOS from the App Store.

Once the app is installed, just enter your ippi username and your SIP password, which is different from your Web password, to log in and make or receive calls.

1. On the third page of the wizard, define the access code that will be used in the Call Routing Table (e.g. 01) and the extension on which you will receive incoming calls from ippi (e.g. 102; you can also receive incoming calls on the Quadro Auto Attendant, extension 00).

If you want calls to fail over through the onboard FXO line, also enable the Failover to PSTN service, then click "Next".

1. Confirm the settings on the last page of the wizard and click "Finish".

The provided account is now registered: you can make outgoing calls through ippi using the 01 prefix (the matching call routing rule with pattern 01* is added automatically to the Call Routing Table).

Receiving incoming calls

The necessary configuration was already created during the VoIP Carrier Wizard, so you now receive all incoming calls from ippi on extension 102.
