[Serusers] Cisco3600 to SER

[smy at addm.com]

Greger,

Thanks for the tip.  Since I'm using Mediaproxy in my SER, there is no t_relay
command in the config file.  (Again, my config is based on www.onsip.org doc)

So what I've done is placing your command at the top (1st commend) in the
opening of route{}.  It improved the situation, since SER kept on resending
INVITEs back to the Cisco via 5080 according to ngrep, yet the trying message
is still sending back to the Cisco via port 5060.  I can't seem to locate
(since I'm still getting familiar with SER) the section where it sends the
trying message in the configure file.  Perhaps you can give me some 
pointers in
where I should be placing the rewritehostport line inorder for the trying
message to be sent on port 5080 back to the cisco.   Thanks!!

The following is the Ngrep I got after the addition of the rewritehostport...
