[cisco-voip] Cisco Voice AND M$ Lync

[Erick Wellnitz]

My experience with the integration is with the audio portions.

First and foremost, you must use CUBE to integrate CUCM with Lync due to
Microsoft's "standards" based SIP implementation.  Microsoft, as usual, put
their own spin on the SIP standards which makes the integration flaky at
best and the CUBE can do manipulations a direct SIP trunk cannot.  I had
QoS configured but still had issues with voice quality when using Lync
conferencing via CUCM.  The last issue I encountered was Lync's logging
features.  The logs would never point to a problem and the logs were
enormous.

Remember as well that Lync is all software...and is on Windows.  It also
took us forever to get the edge servers working properly for external use.
We had three different Premier field engineers on site and got different
answers from each as to what we needed to change.  All said, the basic
functins wored well but the "UC" functions never quite worked right with
Lync.
