Need help trouble shooting Outgoing Caller ID


Well, it really depends on where/what header field your provider wants to see the number contained. Also, post a snippet of what the the first page of an extension looks like in the UCM.


Thanks again. Here is the first of a few shots. Dr 4 will come up at unknown caller. Dr. 6 showed up on once CID as Dr. 6.




Just added phone number to the DOD section of the VOIP trunk


Could this be the problem?


I added our phone to all these spots (DOD, CID for each trunk) and applied changes. Still getting unknown caller CID. Maybe I need a reboot? Maybe need a couple hours?


One more thing. Can you explain this to me?


What does keep CID from inbound call when dialing out mean? Is this for a situation where you would transfer a call from outside to another extension so that extension you are transferring to will see the inbound CID and not the transferring extension?


Try setting the Caller ID at the extension level to the extension number. I think that might solve your problem.


It means to keep the original CID from the caller such that if you have a forward set to an external number, that it will keep the originator number rather than say, the office number, so that the recipient can see who is truly calling and in the event of a disconnect, will have the original number so they can call back if needed.


Isn’t that what I have done here?

It is the extension 1023 and the CID says out phone number 5303420518


I’m suggesting that you put the extension number in the CallerIDNumber field at the top right of the extension settings. Worth a try - I think that might solve the problem. The DoD settings are looking for outbound calls from a certain set of extensions. Your extension isn’t sending its extension number with the outbound call, thus the DoD can’t substitute the number you’ve set there. That, combined with the fact that you haven’t checked the “Keep Original Caller ID” box on the trunk is what is causing your problem (I think.)


Thanks so much for the reply. Just so I understand you want me to try this?




Yes, that’s what I meant. Did it work?


Here are the trunk settings too


Rebooting just in case


:frowning: No Luck. Still shows as Unknown


Could this be part of this issue? Do I need to set it up in the P codes?


Under PBX Settings -> SIP Settings -> ToS there are two settings called “Trust Remote Party ID” and “Send Remote Party ID.” Try checking those two boxes and see what happens.

Also, does the UCM have a public IP? Does it have devices connected to it “downstream” such that it is providing DHCP for those devices? If not, then you should probably uncheck the NAT box on your trunk settings. (Probably unrelated to the Caller ID issue.)
