Inter-Cluster Trunk vs. H.225

Hi,

can someone tell me what the difference between an ICT and the appropriate H.225 connection between a CM and a Gateway is?

What shall be the difference if I connect to CM over H225 instead of ICT? It shall work because CMs are H225 capable, but doesn't work. Singalling goes along the h225 link (including name display ) but we had problems getting audio up. Looks like codec problem, but I didnt find any. Both CMs (one is clustered of two, the other is standalone).

Thanks in advance.....Christian

When you are using another callmanager cluster as a gateway you need to use ICT. There was some extra information that the callmanager needed to exchange that was not there with just the h.225.

Thank you,
