Our company is running through a new VoIP system installation. We are migrating from a Nortel PBX (with Symposium installation for our call center) and during this process decided to go with a Mitel VoIP Phone System.
In the process of the project, I have gone through and upgraded my switching environment to Cisco 2960S PoE (740W) switches. The only thing I haven't replaced as of this time is the Network Core itself which is a 4507R with dual Sup IV's (X4515) in it.
I have configured QOS on the 2960's where we will have the VoIP Servers, end-user workstations and telephones connected but do I need to configure QOS on the core as well? If so, how would I go about this as the documentation that I am using for the configuration requirement on Mitel's end is all related to mls commands which the 4507R doesn't seem to support. I am running IOS 122-54.SG1 on the 4507R right now so I don't think there is anything else I can do from an upgrade perspective to get mls qos functionality.
Anyways, I digress. I hope some of you can give me a hand with this configuration in the time being. Next year (slotted for later in the 2012 year) I will be upgrading to dual Nexus 5548UP's to replace our existing core and then putting in two 2960S 10-gig switches (no power) for the server connectivity. So hopefully this point will be moot at that time.
Thanks to everyone in advance!
