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.

According to your debug log, your format is actually alaw, not GSM.  So, it
looks like Asterisk is transcoding our MOH.  Install the alaw MOH format.
