Re: [SR-Users] [TOPOH] Contact header for 302 Moved Temporarily

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

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.
