Hello, I came into this issue and hope someone can help me.
I have a Callmanager 4.2, connected to an h.323 service provider trough the internet via an IPIP GW. like this:
Callmanager -- ICT -- IPIPGW -- Internet -- h.323 SP
Due to obvious bandwidth issues, a I am using g.729 for the calls, and the calls complete just fine, but when using a service such as transfer (transfering a call to another ip phone), the call disconnects, not immediatly but after a couple of seconds, there is no audio and then disconnects.
I have an xcoder and software mtp registered to the callmanger and available to the devices.
Can anybody please point me in the right direction? Is this even possible?
any help will be appreciated
