[cisco-voip] Cisco inbound Calls to Lync EV User Call shows as "Anonymous"

[daniel at ohnesorge.me]

Hi Joel

A good start would be to run a PCAP on CUCM:

utils network capture eth0 size all count 100000 file lync

While that's running, make the test call. Once completed press CTRL+C and collect the PCAP via CLI (file get activelog platform/cli/lync.cap) or RTMT choosing 'Packet Capture Logs'. 

From there you can use wireshark to filter for the IP address of your Lync and SIP port (ip.addr==1.2.3.4&&tcp.port==5060). Check the SIP headers from there to see if there are any references to Anonymous or if you can see a name/number.

Other things to check would be the SIP Profile associated with the trunk and if there are any SIP Normalization Scripts applied.

Thanks,
Daniel

Running SIP trunks from CUCM 10.5.2 to the Lync mediation servers to route those calls over to that environment. If a call comes in from the PSTN the caller ID shows, but if it is an internal call from a Cisco phone there is no CLID. Looked at the Lync client log and I can see the SIP invite come across from anonymous at domain.com for those calls in question. Anyone ever experience this or have any suggestions, I did follow the Cisco integration guide on how to build out the SIP trunk profiles and parameters that needed to be configured for this integration.
