Forwarding to mobile - does not work when calling from outside

Hello everyone!
help with the problem - Forwarding to mobile - does not work when calling from outside

at the same time, if you call from extension to extension, which has call forwarding enabled, it works

when calling from outside to this extension - it does not work

the log when calling from outside is empty for this action

freepbx 17

No log attached.

The provider probably requires your caller ID, and you have probably sent the caller’s.

I think I understand what the problem is

this trunk provides only 1 channel

everything works with default settings, on a trunk where there were many channels. (more than one)!

There can be many problems why it doesn’t work. I will describe to you the most common ones I have encountered.

  1. Just as the other person writes, it is necessary to set the correct caller ID. The pbx automatically changes the caller ID on an incoming call to the caller ID. The Yeastar S series pbx even have the option to set which identification you want to set when forwarding calls, whether Transferor or Transfree, but only for Attended transfer during an ongoing phone call.
  2. The second problem is voice channels. For the needs of call forwarding, it is necessary to have at least two voice channels at the SIP Trunk provider.
