[cisco-voip] Cisco Voice AND M$ Lync

[Matt Slaga (AM)]

That is quite interesting.  I've done dozens of Lync and Cisco UC integrations and never needed a CUBE in-between.

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.

Any issues as a result of SIP integration documented? I have been making this arguement for about 6 months. We have an extensive Cisco VoIP infrastructure and a Lync system support a subset of users for IM only. The lync system is also "federated" with a group of users we have in office 365. There have been fears that the integration to office in the cloud will suffer as a result of the replacement of messenger with skype. Instead of going with my initial instinct and negatively speak on Lync, I have decided to take a positive approach and present the positives of both products. I will also be making it clear the limitation that are presented by attempting a presence integration to Lync for phone status.

I did on my last project.  It was an easy sell for Jabber on the technical front thanks to the Cisco account team.  My problem was that a prior employee promised the executives the moon, stars, planets, comets, nebula and pulsars with Lync so that investment had already been made.

Your account team should be able to get you a feature comparison.

If someone tries to get you to integrate Lync and CUCM via SIP...run away!  It is a nightmare.

Anyone out there fight the Lync vs Jabber battle? Currently working on a presentation on features of both as well as what can be delivered using both. Anyone care to share suggestions or reference material?

TIA
