IP phone to a pure Lync 2013 EV user show the caller id as “Anonymous”. 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 <a href="mailto:anonymous@domain.com">anonymous@domain.com</a> 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.</p><div><br></div>-- <br><div class="gmail_signature">Joel Davila<br>321.246.7704</div>
