[cisco-voip] QoS and Microsoft OCS

[Matt Slaga (US)]

I can testify on this.  I spend most of my time these days performing OCS and Cisco integrations.

Cisco Pros:
Great devices
Inherent failover (pub/sub) without needing extra hardware (load balancers)
Great feature-set
Constant updates and feature additions
8.0 allows full virtualization

Cisco Cons:
Edge traversal is cumbersome (internet clients)

Microsoft Pros:
Great edge traversal
Ease of use for audio and video calling
Deep office integration
Dial-in conferencing inherent on the product
Federation

Microsoft Cons:
No call-admission control
Requires hardware load balancers for high availability ($$)
Virtualization requirements are stiff (no media servers, no mixing physical and virtual, limited roles allowed virtual)


With this said, the next release of OCS (now called 'MCS') will be a much closer peer-level with Cisco on the voice side.  For now though, the best of both worlds can be found in integration of the two.

Thanks,
Matt

Hi Gary;

As you have tested OCS and I guess that you are deploying it in a production network; can you share with us your experience with it comparing to Cisco UCM in case you are familiar with Cisco part also.

Just wondering if anyone has experience setting up QoS on a network in order to accomodate OCS? I would like to ensure that the OCS packets are tagged and prioritized according to the organization's QoS policy and wondering what ports, etc... I should look for in order to identify OCS traffic.

Thanks!!
Gary
