Hi Daniel,

There is nothing in $rU for this appearing in Kamailio. That is same according to the Packet capture there is not $rU in my INVITE coming from FS. 

This is where in kamailio.cfg I'm getting a 484 Address Incomplete from Kamailio back to FS. 

       if (!is_method("REGISTER") && $rU==$null) {
                # request with no Username in RURI
               sl_send_reply("484","Address Incomplete");
               exit;
       }

So Like I mentioned, if only the $rU part is maintained in the Contact header by TOPOH this would start working as I've experimented by disabling TOPOH and repeated the scenario and it worked. 

Thanks for looking into this,
Regards,
Sammy

Just a quick question, if possible.
I can’t get $ru in reply, cause in reply_route it gives me $ru from original INVITE. In OpenSIPS I’m using $(<reply>hdr(contact)), but how to do this on Kamailio?
Anyway, contact Header from reply was got from tcpdump capture on Kamailio server.

Hello,

isn't the username then decoded from the value of

sip:TOPOH.KAMAILIO.IP;line=sr-N6IAzBy6WBy6MxFwW.qwPSW5ohWINhaYNLu4g9W4OhWI3wKLgRsIpUg5kGs7g9P-W.y6My**

In other words, when the follow up invite in Kamailio comes, can you print the value of $ru with xlog and see if it has username?

Cheers,
Daniel

Not sure it’s a bug, but seems to be topoh module is really lack some configuration.

Hi All,
I've recently stumbled upon this little hitch while using kamailio with topoh module that the Contact header do not contains the User part for the 302 Moved temporarily packet. 

My topology:
UserA<====\ 
                    ->Kamailio<===>FreeSwitch
UserB<====/

The B party has set Call forwarding on their phone hence phone sends a 302 Moved Temporarily to Kamailio.

This is modified in Kamailio TOPOH and sent to FreeSwitch as following
SIP/2.0 302 Moved Temporarily

Which results in a Call Originate from FreeSwitch with RURI as this:

INVITE sip:TOPOH.KAMAILIO.IP;line=sr-N6IAzBy6WBy6MxFwW.qwPSW5ohWINhaYNLu4g9W4OhWI3wKLgRsIpUg5kGs7g9P-W.y6My** SIP/2.0


I am thinking that in TOPOH Module some patch is required to atleast retain the $rU for 3XX replies , not sure if this will break some RFC or Kamailio stability etc !


Thanks,
Sammy.
