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.

"Do you mean if the client hits the hold button? Please elaborate. "

Yes, I mean when I hit the hold button on the SIP softphone, the issue
appears.

I'm sorry for not answering early, I've been quite busy these days... I'll
try to test when I get a chance.

One question, is there an easy way to change from res_timing_dahdi to
res_timing_pthread without uninstalling DAHDI?

The server is not that powerful, is a HP ML150 with a Dual-Core Xeon
3.2GHz with 2GB RAM.
