<tt>Hello Rus,<br>
<br>
The XML scenario is correct, also the REFER b2b scenario is know
to work - for sure you have some routing issues in our opensips
script.<br>
<br>
Do you do any routing in local_routing ? Do you have a pcap I can
look over (send it off list) ?<br>
<br>
Regards,<br>

<div>Hi,<br>
<br>
I'm trying to configure OpenSIPS 1.8.2 to handle the
REFER scenario but when we receive the REFER message,
rather than send an INVITE to the destination in the
Refer-To header, the INVITE flows back up the SIP path
to the caller. I've attached the OpenSIPS config, the
call flow and the refer.xml to this mail.<br>
<br>
</div>
The platform in question has an OpenSIPS instance
listening on port 5060 that handles NAT, when this
receives a call it then calls a second OpenSIPS B2B
instance (the one I am having trouble with) that listens
on port 5080, the OpenSIPS B2B instance then initiates the
b2b_init_request("refer"); causing it to send an INVITE to
itself, then it does some load balancing and makes a call
to our UAS which sends out a REFER telling OpenSIPS B2B to
talk to a different UAS. OpenSIPS B2B then replies with a
202 and hangs up the leg to our UAS.<br>
<br>
</div>
Everything works up until this point. Rather than send an
INVITE out to the address in the Refer-To header which looks
like :<br>
<br>
<<a moz-do-not-send="true"
href="mailto:sip%3A%2B44818118181@192.168.46.103">sip:+44818118181@192.168.46.103</a>;moshxfer=beta_mosh_111111;prefs=1_s6~2_s7~3_h1~4_h2~5_hh~6_s5~7_s8~8_h3~9_..;mode=client;calluid=alphapapa-415f-11e3-9d31-939a1e091c8b;custref=beta;anncset=default;trace=false;suffix=00><br>
<br>
</div>
it sends an INVITE out to the Contact URI of the incoming
call.<br>
<br>
</div>
If someone could please tell me what I'm doing wrong I'd
appreciate it as I'm beating my head against the keyboard at the
moment :)<br>
<br>
Cheers,<br>
<br>
Rus<br>
