Summary:                    [regression] heavy CPU usage when using iax channel
Description: 
When making a call using iax channel, i have a high cpu usage
https://issues.asterisk.org/view.php?id=18#c97%
This does not only happens while transcoding audio, also with the same
codecs on both sides.

after a short time, i get the following cli output:

[Dec 23 11:45:29] WARNING[12300]: channel.c:1045 __ast_queue_frame:
Exceptionally long voice queue length queuing to IAX2/diax-6892

Calling sip2sip has a cpu usage about 1.5% per call

I've attached all threads bt. A single bt gives: "Cannot access memory at
address 0xa".

This the output of gdb:

Core was generated by
`/usr/local/asterisk/asterisk-1.6.2.2.stable/sbin/asterisk -f -vvvg -c'.
Program terminated with signal 11, Segmentation fault.
