Hi Brandon,

get_redirects can be used only from failure_route since it process a negative (3xx) reply - see example: http://www.openser.org/docs/modules/0.10.x/uac_redirect.html#AEN247

the function fetch the contacts from 3xx and adds them as branches to the transaction. Once set as branches, the URIs can not be altered anymore - so you cannot change the contact between "get_redirects" and "t_relay".

regards, bogdan

I am trying to implement call forwarding using the uac_redirect module. My user agents reply with a SIP 302 Moved Temporarily message when the unconditional call forward is set. In the contact field there is something like this...

Contact Binding: <sip:13143212222@ser1.manhattan.sipnetwork.net mailto:13143212222@ser1.manhattan.vtnoc.net>

I need ser to add a plus to that then send the call back out to our pstn carrier. I have tried this...

if  (t_check_status("302"))
    get_redirects("6:2","redirect");
    prefix("+");
    rewritehost("pstn.carriers.ip");
    t_relay();

and putting it in a failure route then forcing that route

failure_route[2] { get_redirects("6:2","redirect"); prefix("+"); rewritehost("our.pstn.carriers.ip"); t_relay();

I even tried

if (t_check_status("302")){ # what to do if device tells us to forward to another number add_diversion("user-forward"); get_redirects("6:2","redirect"); prefix("+"); rewritehost("our.pstn.carriers.ip"); t_relay(); but apparently get_redirects can only be used in a failure_route

Has anyone been able to get this working? On a 302 get the redirects from the contact field using get_redirects append with a "+" and rewritehost somewhere else it seemed so simple. Any help is as always greatly appreciated, especially from daniel@voice-system.ro mailto:daniel@voice-system.ro cause like me he's too far for norway beer.
