> We use dispatcher on Kamailio1 & Kamailio2
> 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?
