Summary:                    CPU usage very high when putting call on MOH
Description: 
Test scenario is very simple, two asterisk servers talking to each other
SIP.

SIP phone dials a extension on the first server which makes a call to the
other server that queues the call (and plays MOH). CPU usage is very
little, as always.

As long as I enable MOH on the SIP client, the CPU usage skyrockets... as
soon as I stop MOH on the SIP phone, everything goes back to normal.

This limits normal asterisk use with many channels involved.

The initial report tests were made with res_timing_pthread.so. After a
while I managed to install DAHDI and use res_timing_dahdi.so on the virtual
machines, but I didn't have a chance to test this particular scenario with
res_timing_dahdi.so.

Thanks for the noload => res_timings_dahdi.so tip, I'll see if it works.

I'll do the tests and report back here.
