 I find it unpleasant to read such a trace. Please really use ngrep to get a
 nice formated SIP trace, or supply the pcap file.

Ok, here it goes again.

Pay attention to the "200: OK" response from the PSTN-GW. I think its Contact 
header should be read by the Cisco GW (calling party), and then send its 
ACK-request with R-URI based on that Contact. But it doesn't happen. Then here i 
think this is the failure. (rfc3261, section 12.1.1 and 12.2.1.2). May i am 
wrong..

What do you think?
I'd appreciate your comments.
