So we are moving from CM 4.2 to 7.1.5.<div><br></div><div>according to this: <a href="http://www.cisco.com/en/US/customer/docs/voice_ip_comm/uc_system/unified/communications/system/versions/IPTMtrix.html#wp1016708">http://www.cisco.com/en/US/customer/docs/voice_ip_comm/uc_system/unified/communications/system/versions/IPTMtrix.html#wp1016708</a> we need all our Router up to 15.0.1M for CM 7.1.3</div>
<div><br></div><div>my questions:</div><div><br></div><div>1. What about 7.1.5?</div><div>2. Why do you need to upgrade to a 15.0 IOS? Could 12.4T work?</div><div>3. If we upgrade IOS to 15.0 will the Routers (VGWs) still work on CM 4.2?</div>
<div><br></div><div>If you have any info on the relationship between IOS and CM I would like to understand it more completely. I have both H323 and MGCP VGW's. Since some of them are H323 does the IOS requirements go out the window?</div>
