RE: [Users] Issues with calls using openser.

4 Jan 2007

Hi!

I think there are several problems:

1. your config is broken. It looks like the caller is a gateway. Usually
gateways are not authenticated by the proxy with digest authentication but
use IP based authentication. Thus, as you challenge the reINVITE, the
gateway has no credentials to answer the challenge and hangs up.

2. The gateway offers µ-LAW and G.729. The Grandstream answers with G.729.
This looks like a normal call setup. Nevertheless the gateway sends a
reINVITE with explicitely offering only G.729. Why? Maybe the gateway does
not support receiving µ-LAW and sending G.729 - thus it sends a reINVITE
to force the received codec to G.729.

Conclusion - fix your config.

Use IP based authentication and TCP (e.g. is_fromgw from LCR module) to
authenticate your gateway to the proxy.
Use digest authentication to authenticate users.

reINVITEs (which are handled in the loose_route() block) can be also
authenticated using the above methods - but not authenticating reINVITEs
is usually no security issue as the totag acts somehow as a "cookie" to
the UAS.

  I changed the codec to ULAW which is defiantly
supported.  I'm thinking
 the
 reINVITE may be the problem but I'm pretty new at openser configuration
 and
 don't see a clear way to detect a reinvite and not auth it.  I did capture
 a
 ngrep of a failed call.  I'll also test xlite or a sipura tonight to see
 if
 it something specific to the grandstream.

 The log shows that you challenge reINVITEs. MAybe this breaks the
 grandstream. Please try without challenging the reINVITE. If this helps,
 then it is a probably a grandstream bug.

 But of course there is the question why the grandstream sends a reINVITE
 at all? This is often a codec problem.

 Please also try to use other client (e.g. xlite) and post complete ngrep
 dumps: "ngrep -q -t -W byline port 5060"

  The SIP UA was a grandstream ATA running the
latest stable firmware.  Prior
  to upgrading to 1.1 and moving to mediaproxy it
worked well with the
 exception of good nat support which is why I would really like
 mediaproxy  to
  work.  Is there anything I should look for in the
sip dialog to
 determine  if
  the client, sip proxy, or the gateway is the
culprit on disconnecting
 the
 call?

 Thanks,

 Shane

 Maybe a bug in the caller's SIP client?
