I am trying to use the uac_redirect module to duplicate the behavior that asterisk performs when it receives a 302-Moved Temporarily from a registered user agent. It basically extracts the number to forward to from the SIP contact address in the 302 reply. For example if "sip: 13143212222@ser1.voipnoc.net" is the sip contact address then 13143212222 is the number (of coarse). It then executes whatever code matches that pattern. This works perfectly for me but ends up making 2 calls because I get the invite, I send it to the UA, and then I do another dial if there is a forward. That of coarse costs me twice as much. I have tried...
if(t_check_status("302")){ # what to do if device tells us to forward to another number xlog("A redirect"); get_redirects("*","redirect"); rewritehost("our.pstn.gw.ip"); t_relay(); return; I simply need it to get the number to redirect to from the contact portion and forward the invite to that number @ our pstn gateway. Any help greatly appreciated.
Hi Brandon,
the important thing to know if that in failure route t_relay() uses as new destination the branches and not the RURI (which was already used in first relay).
the problem is get_redirects adds the new destinations as new branches - these branches, once added are not accessible/modifiable any more; rewritehost() affects the RURI :(.
you can try to relay directly to your GW like: get_redirects("*","redirect"); t_relay_to_udp("our.pstn.gw.ip"); return; hopefully the GW will accept the RURI.
regards, bogdan
