Description:Asterisk 1.4.35

2 SIP clients are registered to asterisk. When 1 client calls the other then
the so called COLP (connected line presentation) feature is not transparent through Asterisk for the according 200 OK messages.

The CALLED client uses P-asserted-Identity header for the connected party presentation and shows the following header in its 200 OK message:

P-asserted-Identity: "Bob Jones"<98005550100@localhost>

see attached wireshark trace

asterisk is at .251, while both SIP clients are on .100
p-asserted-id header is present from called client into 180 ringing and 200 ok messages, but are not included in the forwarded messages to the calling client.

COLP is not supported in versions of Asterisk prior to 1.8. Please use Asterisk 1.8 for COLP support.

Additionally you filed this against CallCompletionSupplementaryServices, which this is not related to.

I had a developer look at the pcap, and he confirms there is nothing odd about the P-Asserted-Identity, and is doing exactly what we would expect.
