I’ve got a PBX (FreePBX Distro) that has two DID’s. A toll free and a local. The toll free is only for inbound calls and the local is used for all outbound calls.
The owner wants it so that the CLID of calls they make (outbound) shows the Toll free DID (even though they are calling out through the local DID) so that the local DID remains “hidden.”
As I understand it, this is possible by setting the “from” field as the TF DID and setting the P-Asserted-Identity as the actual local DID CLID.
A) Am I understanding this correctly
B) How do I accomplish this in the FreePBX web UI
I see in advanced sip settings I need to set “SIP sendrpid = pai” but I’ve also read that this only effects NEW extensions. How do I apply this setting to existing extensions (if this even is the proper way to achieve my goal).
