[Freeswitch-users] Problem with gateway registration

[Nicolas Brenner]

That happens with both gateways though, one works and the other doesn't.
Would the rport have anything to do with the registration failing?

The big difference to me is that the working gateway replies a 401
Unauthorized containing:

 WWW-Authenticate: Digest realm="pxextmy.redvoiss.net",
nonce="4acac8fe248a9075a13773274684392a65a40240", qop="auth".

Whereas the non-working gateway's 401 has:

WWW-Authenticate: Digest realm="216.72.10.39",
nonce="4acac08249c439decb2bea539282faf755c80b0c".


What does the qop parameter stand for? Apparently because of that parameter,
FS sends a new REGISTER including this:

Authorization: Digest username="xxxxxxxxx", realm="pxextmy.redvoiss.net",
nonce="4acac8fe248a9075a13773274684392a65a40240",
cnonce="h1DCSizTEi2eMQAdCe9KJA", algorithm=MD5, uri="sip:
pxextmy.redvoiss.net", response="05adb2a7f9d7772e57dc846257484f5d",
qop=auth, nc=00000001.

Instead, on the non-working gateway case, FS sends a REGISTER with this:

Authorization: Digest username="yyyyyyyyy", realm="216.72.10.39",
nonce="4acac08249c439decb2bea539282faf755c80b0c", algorithm=MD5, uri="sip:
216.72.10.39", response="8311db7666779df89d5223e16a611826".


Notice the absence of the qop and nc parameters. I'm guessing the lack of
those parameters causes the gateway (SIP server) to use another nonce and
hence reject the mismatching REGISTER.

BTW, registration from an X-Lite softphone works.


Thanks!

Nicolas
