Audio issues

Hi,

audio seems to be still a game of luck with current ekiga's stable
release. Sometimes when I answer an incoming call, I can't hear the
caller and he can't hear me. Sometimes I can hear him, sometimes I can't
but he can. There doesn't seem to be any rule for this behavior. I
observed this with all 3.2 versions. It's independent of the sip
provider or the caller.
All three audio devices are set to default, I have no sound daemon
running (like esd or pulse). Ekiga, opal and ptlib are self-compiled on
Ubuntu Linux.
Once this problem occurs, I have to restart ekiga to get sound working
again properly. I'll send a d4 output a soon this happens again.
Anyone else having this problem?

Chris

I've seen this on a number of occasions on Fedora as well. Fedora uses
PulseAudio but that doesn't seem to be the issue. I've even had some
report that they've recompiled ekiga 2 from F-9 and go back to that.
It seems very hit and miss as to what causes the issue and its very
hard to track down.

It sounds like NAT issues.

The best is to always start ekiga like this:
$ ekiga -d 4 2>/tmp/debug.out
and when the problem arrives, you get the output.

This could be the "pdu too large" problem, but that bug is reproducible...

The problem is that ekiga v2 works and v3 does not sometimes...

No, this is independent of NAT. And if it wouldn't be, this problem
should be reproducable then..

What is the cause then ?

That was my first response as well but then surely they'd see the
issue with ekiga v2. I think part of one of the problems is the
openser issue but I'm not sure if that was fixed with the last 3.2.5
and associated ptlib/opal issue. I'm waiting for the new ekiga build
to be pushed out to fedora updates-testing for that person to confirm.

I would assume a NAT issue as well. There are routers which according to
Ekiga's NAT detection change their role, my Fritz!Box e.g.. In the -d 4
logs look for the lines containing stun. When I am continously starting
Ekiga and make calls Ekiga detects cone NAT. The first time or after
some inactivity it reads port restricted NAT.

If you are talking about the openser issue that prevents registration,
that's another problem and it is due to misconfiguration of openser...

Referring to the bug below. There's no reference to a configuration
problem in the bug and its still open.

Well, the problem occurs in a company's network with direct internet
access. I suppose this effect of changing NAT behavior you're talking
about is related to low-end home routers.
stun.ekiga.net tells me in ekiga's logs constantly that I am behind a
"Symmetric Firewall".

I really hate to say this, but I'm currently giving Linphone a try. So
far there are no such audio problems.

You have not sent us any debug output so far for these audio problems.

As I already wrote in an earlier mail, I'll do so as soon as the problem
  occurs again. As I said, this issue is hardly reproducible so it's
hard to get a log.

Disable the network detection then, if it is for local access.
