Is it possible to use triggers and automations to route Talk tickets based on the Talk number which the call was received like you can with emails?
Using the Comment text condition in triggers it is possible to identify which number was called and run a trigger.
When a Talk ticket is created, the ticket description includes a "Call To: +1 (800) 867-5309" string. You can use this information in the Comment Text condition to identify and route Talk tickets.
Using the Comment text condition for each phone number you can create a trigger that will run when a ticket is created and the "Call To" string is present for that number.
Below is an example of a trigger to route voicemails after they have created tickets.
