Hi Benko,
the UAS must put in contact of 3xx exactly the address where the call should be re-routed. If the UAS want to re-receive the call but using different port/proot, it must use its IP in the host part.

Hello!
Thanks for the fast answer. No, proxydomain.org points to 2xx.xxx.xxx.x06 which is the openser-host, 6x.xxx.xxx.x93 is the user agent. Is the reply from the UA wrong, should it contain it's own ip as redirect-contact?
regards Christian

Hi Benko,
not sure what is the problem? isn't the redirect contact correct?? doesn't proxydomain.org points to 6x.xxx.xxx.x93 ?
if so, isn't enough to do t_relay() after get_redirects() in failure route?
regards, bogdan

Hello!
I'm having a issue with a 302 moved temporarily from a UA i want to attach to my proxy. The UA replies to a INVITE from the proxy with a 302 MOVED TEMPORARILY and i'm using "get_redirects" from the uac_redirect-module to extract the contact. However, i don't know how to continue from there as the domain part in the redirect-contact is the hostname of the proxy but the port is 5065 and transport=TCP (see debug for details) and if i simply relay it, it would be relayed back to the proxy on the wrong port 5065.
I guess i could use the request branch pseudo variable($br) and extract the port from it(or change the domain-part to the actual domain/ip of the UA and relay it), still i don't really know how to do it.
This is the sip-trace of the relevant dialog part:
2xx.xxx.xxx.x06 is the openser-host, 6x.xxx.xxx.x93 is the useragent

Either i'm lacking understanding of the openser functionalities and sip redirect in general and simply don't see how this could be accomplished easier or i guess i need to grab "sip:4989111111@proxydomain.org:5065;transport=TCP" and extract the right port and protocol from it to relay it correctly(don't know how to do that though), i'm not sure. Currently i'm using a simple t_relay("tcp:6x.xxx.xxx.x93:5065"); to get it working, but i'd like to implement it in a more generic way.
thx for all answers!
best regards christian
