Description Aaron Seibert 2009-07-28 20:59:49 UTC

Steps to reproduce:
1. Configure Ekiga for Asterisk Sip account
2. Set ekiga client and sip.conf entry to only allow ulaw
3. Call ekiga client, and push accept on the incoming call popup

Call will not pick up, and ekiga then "soft"crashes (becomes unresponsive)

Other information:
This works fine with all other soft and hardphones that I've tried.  Rejecting the call works, and all outgoing calls from client work.

Comment 1 Eugen Dedu 2009-07-28 21:11:05 UTC

Aaron, what ekiga version do you use?

Comment 2 Aaron Seibert 2009-07-28 23:11:13 UTC

3.2.5

Comment 3 Damien Sandras 2009-07-29 06:25:10 UTC

What distribution?
How was Ekiga built?

Obviously, it works for others, so such a weird bug is surprising.

Comment 4 Aaron Seibert 2009-07-29 12:05:34 UTC

Fedora 11 x86_64, installed from yum repo

What makes it even more wierd is that it works fine for me at home, F11 x86.  A quick look at /var/log/messages shows nothing as well.  Maybe ekiga isn't playing nice with one or more apps that I have running on my work computer?

Comment 5 Eugen Dedu 2009-07-29 14:44:24 UTC

Aaron, please try again inside gdb, as shown on the wiki debugging section, and attach the output.

Thanks, I pushed your bug to opal tracker, https://sourceforge.net/tracker/?func=detail&aid=2829208&group_id=204472&atid=989748

Comment 11 Damien Sandras 2009-07-30 06:25:53 UTC

Actually, it seems to be PulseAudio that blocks the device opening, hence blocking Ekiga.

Please report that bug to the PulseAudio guys.

Done. Ticket number 613 with PulseAudio
