Frequent questions
Telegram gateway is extremely convenient if your audience needs the ability to make free calls to your company from anywhere in the world via Telegram. Its use is not only comfortable for Telegram users, but can significantly reduce your company's international telephony costs and simplify its infrastructure.
Your company employees will also be able to make outgoing calls on behalf of the company's Telegram account (but not mass cold calls).
The ability to receive calls via Telegram can seamlessly complement business processes in the following industries, for example:
The link to the Telegram account for calling your company can be placed in company blocks on the website, in support bots and chats, Telegram channels and communities, on product packaging, ATMs, etc.
If your company already promotes its products or services on Telegram, or if you communicate with your users through Telegram bots, then adding voice calls is also a good idea, gives you a significant competitive advantage and increases conversion rates. Communicating by voice often takes much less time and effort on the part of the caller, while being more informative, and many customers will prefer this method of communication.
Also, the implementation of a gateway greatly increases the privacy of conversations.

It is often convenient to create a separate Telegram account for voice calls and give it a clear username with the name of your company (for example @somecompany_calls).
But in some cases it may be convenient to register a Telegram account for the same number to which users already call you.
The number for registering a Telegram account must support the ability to receive SMS, and a message with a confirmation code will be sent to it.
IMPORTANT: If you start a Telegram account only for calls, don't forget to renew and activate it with your service provider. Many telecom operators take numbers back to themselves and can resell them to other customers if they are not used for a long time.
A convenient solution may be to purchase a virtual number to register an account on the Fragment platform, so it will not be tied to a telecom operator.

Connection and configuration of Telegram account for calls on the SIP.TG side are performed via our Telegram bot @siptg_bot. Part of the settings should be made on the side of PBX.

If you do not plan to process text messages (for example, via hotline.tg) coming to the Gateway account, then to prevent users from texting their questions to the accounts, you can activate the Autoanswer function in the Gateway settings and set a text message that will make it clear to users that this account is for calls only. This message will be instantly sent automatically in response to any message from the user.

You can. Keyboard display is activated via @siptg_bot in the Gateway settings. The keypad is sent to the user as a message during the call, to use it you just need to return to the chat with the Gateway account.

You can. The format of internal numbers is set through the number conversion rules. If a user's message matches the specified mask of internal numbers, the call will be redirected to this number at once. About number conversion rules
You can also bind several SIP-accounts to one Gateway account, in which case the user will automatically select a line for the call (depending on the entered number and the set number conversion rules), or the user will be able to select a line for making a call (if two or more accounts meet the condition).

Practically any where telephony is available. To integrate the Gateway with CRM it is enough that your telephony module (PBX) supported the function of connecting external numbers (was not locked to use one operator), or it was possible to connect another external SIP-connector.
Features of integration with a particular system is whether the system is designed to work with multiple incoming and outgoing lines (if you need to call from one system and conventional telephony and Telegram).

Telegram bots do not have the ability to receive and make calls, so
if you already use a bot for support or sales, it is often convenient to add to the bot's welcome message or contact block an offer to call the account for calls.
For integration with other software products, please contact support. We have a special offer for large companies and service providers.

If you use systems for joint communication via CRM (Wazzup, Radist, Hotline.tg, Textback, etc.) tied to full-fledged Telegram-accounts, then in the profile of these accounts the possibility of making calls is preserved.
By adding a gateway to the used Telegram-accounts it becomes possible to make calls via PBX, make records of conversations, tie them to the contact card in CRM, distribute calls between employees.

It's really reliable. Telegram's infrastructure and fault tolerance are among the best in the world. To establish calls to Telegram's central servers, only a short call is made, after which the call is routed through the relay-server infrastructure, or goes directly p2p-connected. Algorithms for the transmission of voice calls for Telegram are adapted even to work with weak and unstable internet connections.
The infrastructure of SIP.TG servers for "landing" calls to SIP-PBX has already been deployed in data centers in Moscow, Frankfurt, Amsterdam, London, Washington, D.C., Tashkent, Minsk, and is rapidly scaled if necessary.
The service has been operating since 2019, during which time many scenarios of its use have been fine-tuned.

The main advantage of the Gateway is that a user from any country can call a business for free via Telegram to its regular PBX, and many users can call simultaneously to one Telegram account. The called user can be called back without restrictions. Also, if a user has already had some correspondence with him via the Gateway account, you can call him without fear of being banned by Telegram. All calls can be recorded and analyzed on PBX.
For outgoing cold calling on the database of phone numbers Gateway is not suitable. Telegram's anti-spam algorithms do not allow you to make a large number of outgoing calls to users with whom you have not had prior correspondence, from whom you have not received your first call, and whose contact list does not include your account.
Tell our support team about the nature of your company's calls, and we will tell you more about how you can adapt Telegram calls to your business.

Of course. Our support team regularly answers user questions on a first-come, first-served basis. If you want to book time for personal help with setting up or implementing SIP.TG, or if you need regular technical support for our solution, we provide paid priority technical support, configuration help and consultations.
No. As far as we know, no other popular messenger except for Telegram supports both multichannel calling (watsap has no multichannel) and gateways to SIP telephony, their calls are not as stable and not as well adapted to a weak Internet connection. Telegram is the best messenger for voice calls and for business today.
Our Gateway works with all office and virtual PBX, as it is connected as a regular SIP-trunk, it is absolutely standard procedure for almost any PBX. For example, supported registration with such PBX as Asterisk, 3CX, Panasonic, Oktell, FreeSWITCH, SipXecs, Yate, FreePBX and many others. Depending on the equipment configuration there may be some differences in the order of connection, but in general there should be no problems.

It doesn't. Our solution is based on our own code supporting WebRTC protocol, it is perfectly compatible with modern Telegram software kernel. Problems with tg2sip library stopping support of old OPUS codecs in Telegram clients don't concern us in any way.

Data
privacy
The SIP.TG server infrastructure is secure, stable and productive. But if there are special requirements for confidentiality of call data and accounts, or there is a need to handle a huge number of calls with performance guarantees, we allow you to deploy the infrastructure for the Gateway on your own modules.
The SIP.TG platform can transparently integrate with any existing infrastructure and products of telecom operators and large companies.
