Summary:                    CCM sends multiple INVITEs which causes MusicOnHold
to execute on a channel
Description: 
Found this for a client who is using a CCM gateway and terminating calls to
SIP phones attached to Asterisk.

I've added some traces from the console with history dumped. You'll notice
in the good calls that you get 3 or 4 INVITE,100,200,ACK loops, then the
CCM stops sending the invites, and the call remains setup.

In 1.2.26.2, you'll see that happen, with the Starting Music on
Hold/Stopping Music on Hold each time that loop happens. On 1.2 though, the
music on hold never actually is heard. On 1.4, when the same thing happens,
the music on hold actually is executed and does not stop.

This is preventing him from moving to 1.4.

Should I assume that this patch is written against the 1.4.18 release
tarball?  Seems to have applied OK.
