[Asterisk-Users] chan_sccp bug / problem

[Remco Barende]

Hi list!

I'm having some problems with chan_sccp and a Kirk IP600. Basically the 
handsets work (they emulate a Cisco 7940) but I have the following issues:


1. If a handset is in a conversation and there is a new incoming call,
the incoming audio is muted (but the other party can still hear anything
spoken on the handset). What is normal Asterisk behaviour, that a handset 
is left alone when it is busy or is there still signalling going to the 
handset even when it is in conversation (I guess that is what is happening 
now).

2. Asterisk seems to crash at random, sometimes after an hour sometimes 
after two days. It just exits with a Segfault:

I did a trace on asterisk and this is the result:

The box is running a RHEL Rebuild for x86_64 arch, and Asterisk 
1.0.5-BRIstuffed-0.2.0-RC5

I guess this is a bug, not a feature?
