# TG2SIP

TG2SIP is a Telegram<->SIP voice gateway. It can be used to forward incoming telegram calls to your SIP PBX or make SIP->Telegram calls.

## Requirements

Your SIP PBX should be comaptible with `L16@48000` or `OPUS@48000` voice codec.

## Usage

1. Download prebuild versions for supported OS from CI or compile it yourself.  
[Ubuntu 18.04 Bionic](https://ci.appveyor.com/api/projects/Infactum/tg2sip/artifacts/tg2sip_bionic.zip?branch=master&job=Environment%3A%20target_name%3DUbuntu%20Bionic%2C%20docker_tag%3Dbionic)  
[CentOS 7](https://ci.appveyor.com/api/projects/Infactum/tg2sip/artifacts/tg2sip_centos7.zip?branch=master&job=Environment%3A%20target_name%3DCentOS%207%2C%20docker_tag%3Dcentos7)  
Prebuild binaries requires OPUS libraries (`libopus0` for Ubuntu, `opus` for CentOS, etc).
2. Obtain `api_id` and `api_hash` tokens from [this](https://my.telegram.org) page and put them in `settings.ini` file.
3. Login into telegram with `gen_db` app
4. Set SIP server settings in `settings.ini`
5. Run `tg2sip`

SIP->Telegram calls can be done using 3 extension types:

1. `tg#[\s\d]+` for calls by username
2. `\+[\d]+` for calls by phone number
3. `[\d]+` for calls by telegram ID. Only known IDs allowed by telegram API.
