[Users] Cisco Gateway Disconnects the call

Wed Jul 12 18:31:54 CEST 2006

Hello,

the "***** [Remaining retries omitted …]" are very important. The issue 
is that the ACK is not routed properly to the gateway. The caller's 
phone is broken, does not handle properly the record-routing. the ACK 
has no information to route the message to the gateway.

As you can see the r-uri is set to sip server and the Route header as 
well (in the Route headers matters he host part and the port). So, 
either the r-uri or the Route header has to be the address from the 
Contact header of the 200 OK reply,

Cheers,
Daniel
