[cisco-voip] CUCM Shared Line Appearance (SIP phones)

[Daniel Pagan]

The request-URI in this case is the PKID of the DN followed by the IP address of the phone. Check it out:

https://10.10.13.100/ccmadmin/directoryNumberEdit.do?key=ae97ba4b-2397-4b52-5ddc-07589fb380ab

^^^URL of a test DN.
Key= ae97ba4b-2397-4b52-5ddc-07589fb380ab

INVITE sip:ae97ba4b-2397-4b52-5ddc-07589fb380ab at 10.10.31.6:50926;transport=tcp SIP/2.0

^^^ Check out the request URI above.

Hope this helps.

Subject: [cisco-voip] CUCM Shared Line Appearance (SIP phones)

Hi all. When CUCM sends a SIP Invite to shared lines on SIP phones the user portion contains some sort of (what appears to b) a randomly calculated alpha-numeric string. Is there any information or documentation available on how Cisco actually calculates what this string will be?

Here is an example of a SIP Invite going to two SIP phones sharing the same phone number

INVITE sip:8cc951b7-86b6-0c74-1e4d-c0108c268dc2 at 10.232.50.81:49422;transport=tcp SIP/2.0
INVITE sip:8cc951b7-86b6-0c74-1e4d-c0108c268dc2 at 10.232.50.91:51945;transport=tcp SIP/2.0


Thanks,
Mark
