I have an extension.conf which calls a sip phone and the console in parallel. exten => _1${EXT_BARRY},1,Dial,sip/${EXT_BARRY}&Console/dsp This is done to use the console speaker as a load ringer for extension ${EXT_BARRY} The process works, but while the call to Barry is active, and after its completion, one process starts using about 99% of the CPU. I watch CPU usage with 'top'. My * is a CVS checkout of about a week ago, I am running kernel version 2.4.22 and the problem occurs on channels set up through sip or capi. Anyone any ideas?
