Forwarding/Twinning CID w/SIP trunks

[Josephl8907]

I'm having trouble on a 11.0 SE with SIP trunks sending the original calling parties number.

Forwarding a user does not send the original calling parties number. Forwarding sends the DID.
Twinning sends the calling parties number.
Also assisted transfer sends the calling parties number as well.

I'm no SIP expert. Just though Id throw that out there. Any guidance will be greatly appreciated.

There's an issue with 10.1 SP3 and 11.0 where it doesn't send diversion header if you don't have a desk phone logged in.

Currently waiting on a CP for that issue.

Thanks for the reply J78. There are users that have phones registered and giving the same problem.

What are you expecting to see in what scenario?

Calls forwarded to a cell phone are showing the users DID. Would like to show the calling parties number on the cell phone.

You need to compare the INVITE you're sending to the SIP provider when this is CLI is working and when it's not.
