We have the following setup and I am having trouble passing the PRACK with correct protocol to the provider.
The invite goes fine from UCA up to the provider and the provider responses arrive to UAC fine.
The PRACK from UAC to kamailio1 goes fine to Kamaili02 but, Kamailio2 uses the UDP socket to send to the provider so the PRACK does not arrive to the provider and the call is canceled.
If the provider is on UDP everything works fine.
Below I have the trace. What should I look for in the config to resolve this wrong protocol/socket on the PRACK?
