If your employees use CRM system for processing incoming and making outgoing calls, then to integrate the Gateway with CRM It is enough that your PBX supports the function of connecting external numbers (it was not locked to the use of one telecom operator), or it had the ability to connect another external SIP connector.
Our Gateway for Telegram-calls successfully works with systems such as Bitrix24, AMO CRM,Retail CRM, SalesForce CRM, Pipedrive CRM and many others. In most cases, integration occurs through a plug-in module for SIP telephony (virtual PBX).
Some CRM- systems, for example, Bitrix24, support the connection of additional external SIP connectors (except for the main PBX). In this case, the Gateway can be connected precisely as an external SIP connector, regardless of what kind of PBX is used and whether it supports the ability to connect external lines, which are also called trunks (VoIP Trunk).
Typically, when configuring the Gateway
the registration option PBX->SIP.TG is used (the bot receives the details for connecting to the Gateway and they are indicated in the PBX settings). Most popular virtual PBXs (onlinepbx, uis, etc.) and office PBXs (Asterisk, Panasonic, Oktell, FreeSWITCH, SipXecs, Yate, FreePBX, etc.) provide this opportunity.
