Thank you for the response Mike, I did run into a CDR bottleneck as well and have already disabled it,
> module show like cdr Module Description Use Count Status Support Level 0 modules loaded # grep enable= /etc/asterisk/cdr.conf enable=no At this point I'm really just not sure what the current bottleneck is and how to prevent the tasks for pooling. I expected that the CPU would cap out before this occurred. I do feel like there must be something I'm missing but just can't to it. Any further suggestions are very welcome.

I removed/disabled the CSV CDR module, kept on the SQL CDR only and things have been working fine ever since.

Unfortunately the tests produce the same results.

You will find it less taxing on the server if you have MoH files and sounds files available in all the possible native formats. Then Asterisk can use the appropriate one for the channel without transcoding. On my systems I have MoH and sounds installed in wav, ulaw, alaw, gsm and g729. They will also sound better than transcoding from the gsm versions.
