Specify the form in which the number of the caller should be transmitted to PBX . You can set the value priority, as well as a prefix or suffix before the value to distinguish calls that come via Telegram from regular calls.
There are 3 values available for Caller-ID:
- userid(we recommend using the user'smain, internal Telegram-id, there is always)
- username (in Latin characters and numbers, may not be set by the user)
- phone (the phone number linked to the account can be hidden by the privacy settings)
You can also specify what to send to PBX as the Caller-Name field.
This step can be skipped during the initial setup phase.
Important! If you specify a prefix or suffix for the Caller-ID, you must save them when making outgoing calls from PBX to Telegram.
