Conferencing with Ios Gateway

I have a remote Ios Gateway with Ios version 12.3(8)T and Pvdm2,conferencing worked correctly for 3 months.

After reboot of Publisher CallManager unfortunately Ios Gateway conferencing doesn't work.

I didn't change configuration in Ios Gateway and Callmanager.

http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123cgcr/vvfax_c/callc_c/ccm_c/intcnf2.htm

This document of Conferencing and transconding explain me how correctly configure Ios Gateway.

I found only difference : my Ios Gateway have version 12.3(8)T but Pvdm2 is supported only with 12.3(11)T.

In past i replaced Ios version 12.3(11)T with 12.3(8)T to solve "Dsp not found"problem (Cisco Tac).

Please,could i replace Ios version 12.3(8)T with 12.3(14)T??

Many thanks and sorry for my bad english.

Yes, you can load 12.3(14)T. The best place to get info on what is supported for CCM & IOS is to look at the CallManager Compatability Matrix. This matrix can get busy with all of the releases of CCM & other products but it is the best source:

You will see the MIN version of IOS suported with any version of CCM.
