We integrate our UC560 with Microsoft Lync and are having a strange problem which we have logged with Microsoft, the issue I have is that they advise IOS needs to be 12.4 and above and even though we are running 15.1 they are not convinced!!
The reason they believe we are still on IOS 12.x is because our SIP headers user agent says we are, as below:
Does anybody know why the gateway shows up as IOS 12.x even though a show ver shows the below...
Cisco IOS Software, UC500 Software (UC500-ADVIPSERVICESK9-M), Version 15.1(2)T3c, SBTG Special Small Business Support: http://www.cisco.com/go/smallbizhelp Copyright (c) 1986-2011 by Cisco Systems, Inc. Compiled Thu 09-Jun-11 13:03 by SBTG
ROM: System Bootstrap, Version 15.0(1r)XA, RELEASE SOFTWARE (fc1)
Any help would be appreciated or if this is correct, does anybody know the official reason why it is like that (backwards compatibility or something similar) so that I can stop Microsoft using this as a reason as to why the Lync installation has an issue.
It is a UC560 running CME 8.1 on IOS 15.1(2)T3c, as far as I am aware you cannot modify the user agent but I have just stepped through our config line by line as well as looked for various "user agent" related phrases and can find nothing on the server that would make it say 12.x.
I know the IOS is 15.1 as I tried some "new commands" that are only available in IOS 15.x and they worked so I am sure that this is an IOS 15 box.
Also... having looked at most of Ciscos documentation that has SIP traces in them they also have a user agent of 12.x so I think this is just normal behaviour.
Our issue with Lync is that when certain mobile phones (only out company phones) call a response group they will be placed on hold for eternity they hear the hold music but the response group will never answer, if you call from a non company mobile phone it is fine. All other types of calls from one of our company mobiles are fine (direct Lync DDI's as well as things like the conferencing centre) it is just when you call a response group.
Our CME has no specific configuration that could be making this and the fact that you hear the Lync response groups hold music makes me think that the issue is in Lync!
Any help would be greatly appreciated as Microsoft are trying to kick it back to Cisco and dealing with Cisco SBS TAC will be a nightmare as we will have the old "not supported due to it being CLI config" challenge!
Any help or suggestions anyone has would be greatly appreciated!!!

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
