<div class="moz-cite-prefix"><tt>Hi Satish,<br>
<br>
It is an known issue that OpenSIPS does not increases the cseq
number when performing UAC auth against another party. Asterisk
does not like that and consider the new branch INVITE with
credentials a simple retransmission (even if it has a different
VIA-branch :P) and discards them - this is why you get that
timeout from asterisk.<br>
<br>
We have ongoing work (hopefully to be ready in 1-2 weeks) for
increasing the cseq number is a sip-wise manner. Just keep an
eye on the mailing list.<br>
<br>
Regards,<br>

Hi,<br>
<br>
</div>
my Opensips (UAC) registered to PSTN gateway
and now i am trying to call using my SIPphone
which is register to opensip but no success. I
am getting 407 Proxy authentication issue.. I
am using following method but it didn't work.
I need solution badly.. <br>
<br>
</div>
PSTN gateway sending 407 Proxy auth and then my
Opensip sending 407 proxy auth to SIP phone. <br>
<br>
</div>
Does anyone has any working example or some kind
of document? I haven;t see any single doc anywhere
in Internet about uac_auth issue<br>
<div>
<div>
<div><br>
<br>
<br>
<pre>modparam("uac","credential","username:domain:password")
route {
....
t_on_failure("2");
t_relay( "udp:ip_addr:5060" );
...
}
failure_route[2] {
uac_auth();
t_relay("udp:ip_addr:5060");
}
