Fax-Relay & Fax Pass-Through Integration

[a.janssen]

Hi,

I have the task to migrate a network from Fax Relay to Fax Pass-Through. Some gateways are connected via H.323 and some via MGCP to the callmanager 4.2. The dial-peers on the H.323 gateways point to the callmanager. Can I migrate some gateways to Fax Pass-Through without loosing connectivity? How is the call flow in this case? I guess a direct RTP stream between the gateways won't be possible, caused by the different transport types. Will the Callmanager terminate the call flows? If yes, how is the affect to the Callmanager cpu? Sorry for so much questions, but I can't find anything about that.

Regards

Andre
