We've got CUCM 8.6.2 and have a SIP trunk from our provider going through a CUBE. Today everything is working well. Because of a few ordering/design issues, we're getting ready to port one of our remote site's numbers to our SIP Trunk and then route them over the WAN. Inbound calls won't be an issue but we'd like all the remote sites outbound calls to show their name and caller ID information.
Right now I have the name and caller ID specified on the trunk but I don't see anyway to have it change based on the origin of the call. I've seen where you can go to the line level to define the caller ID but I rather do it somewhere in-between if it is possible. I tried adding another trunk but it didn't like the same destination IP. I don't have much expereince with SIP as this is our first trunk.
