[OpenSER-Users] Reg. conditional processing of invite - sr-users

13 Nov 2007

HiThanks for the reply, I however, do not know how to implement what you mentioned in your
earlier mail. can you detail the steps? One of the openser users has suggested the
following:
*******************************************
if (is_method('INVITE'))
{
 # check if from URI domain equals 911operator.com
 if ($fd == '911operator.com')
 {
 # relay stateless using request URI
 forward();
 exit;
 }
 else
 {
 # relay statefull using request URI
 if (!t_relay())
 {
 sl_reply_error();
 };
 exit;
 }
}

However, the function forward(); does not parse and gives error bad arguments. Can you
suggest how to get this code working? I need it working asap.
Thanks again,
Padmaja
Hi Padmaja,

There is no other way around but just to implement a call back service 
on your proxy. Save in DB the last caller hitting the 911 service and 
when receiving the 8911, just load it and fwd to it.

  Hi all,

 I have an issue, where the sip user dials 911 number and hangs up. The 911 
 operator then calls back to the user using the call back command provided 
 earlier say 8911 (there is a b2bua that interprets the call back number and 
 routes the call to the specific user). This number is to be routed via the 
 openser proxy to the b2bua. However, when the 911 calls back, proxy treats 
 this number as a username and since there are no registrations to this 8911 
 number (though this entry is present at the proxy, no device has registered 
 with this number), it sends back "404 Not found". How can this be 
 circumvented?

 Thanks,
 Padmaja
