<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>I’m curious about this document as it only lists the IOS version required for CME / SRST. We still are UCM 7.1(5a) with IOS 12.4(24)T3 and aren’t having any issues. However, we haven’t done a whole lot of SRST testing... Maybe I should do more.<BR>

</SPAN></FONT><BLOCKQUOTE><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>So we are moving from CM 4.2 to 7.1.5.<BR>
<BR>
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<BR>
<BR>
my questions:<BR>
<BR>
1. What about 7.1.5?<BR>
2. Why do you need to upgrade to a 15.0 IOS? Could 12.4T work?<BR>
3. If we upgrade IOS to 15.0 will the Routers (VGWs) still work on CM 4.2?<BR>
<BR>
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?<BR>
<BR>
Thanks<BR>
