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.

Setting this status to feedback since it doesn't appear to be an issue with
Asterisk, but leaving it open per the reporter (kreator) so he can leave
feedback once it is resolved on the Cisco side of things.
