I have a situation where each extension on a system is provided with its own local telco number, a US telephone number and a UK telephone number. The system has a DID pri for local connectivity, a US multi channel SIP trunk with multiple DID’s for US connectivity and a UK multi channel SIP trunk with multiple DID’s for UK connectivity.
The problem is that I need to send the right CID depending on which trunk is selected. In FreePBX I can setup the extensions to send one CID when they access any of the three trunks but not three separate CID’s that are trunk specific.
Has anyone any suggestions how I might achieve the required result? Help would be very much appreciated.
