[Serusers] ACK not sent

Tue Jun 7 16:45:03 CEST 2005

 It is one call - the IP addresses are: the dialled phone (142.178.21.214), SER (142.178.218.210), the application platform (142.178.213.169) and the re-routed called party (142.178.21.182). The proxy of the application platform uses 142.178.213.201 for return messages as well just to confuse
things. The cfg works fine if I don't engage the application platform in the call.
