Hi. I’ve just recently started using a SIP trunk from VoIP.ms instead of the FXO lines. The trunk has multiple DID numbers, each of which has their own Inbound Route in the UCM.
Example: DID 1 goes to Phone A, DID 2 does to Phone B.
What I’d like to have happen is: Outgoing calls made from Phone A, have the caller ID show the Caller ID as the phone number of DID 1.
Outgoing calls from Phone B should show CID of DID 2.
I have set CID’s accordingly in the Extension configurations.
However, after experimenting with the VOIP Trunk settings, I get:
- On the Advanced tab, If I check the “Send PAI Header” and fill in the PAI Header manually with CID info then all outgoing calls, no matter where they originate from, use that CID–which is understandable. I can see where that would be great in a situation where a number of DID’s are used for incoming calls but a single CID (say, main office number) is used on outgoing, so people receiving the outgoing calls would always see the main office number on their display.
My situation is a bit different. I have a UCM 6104 at home and have two DID’s–one for a ‘Home’ number, one for an ‘Office’ number. It would be nice to have the outgoing CID’s match, so that if I call back someone on the ‘Office’ line it doesn’t show the home CID, or vice versa.
- If I uncheck the “Send PAI Header”, then the outgoing CID goes to the SIP Account specified in the “From User” field from the Basic Settings tab–unrelated to any DID.
I’ve tried checking/unchecking various combinations of other parameters, but have not stumbled on the right combination.
Can anyone tell me,please, what combination of settings needs to be in place to have the CID specified for an Extension to be used for the outgoing call CID?
Any help would be appreciated. Thanks.
