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

Any idea what’s wrong?
