Summary:                    Calls Looping back into call groups cause confusion
or overload.
Description: 
If one has a call or ringing group implemented by a Dial command:

exten => 140,1,Dial(SIP/112&SIP/113&SIP/116)

and one of the SIP phones in that Dial command sets call forwarding to the
group exten (ie SIP/113 sets call forward always to 140), then any calls to
the group (140) results in multiple calls taking place that (with enough
phones involved) can bring the entire Asterisk system to its knees.

There are similar problems with queues getting deluged by these looping
calls.

Initial testing looks good - thanks for your effort.

I'll roll it into a live (albeit modestly sized) system and report back in
a few days.

Are you planning on producing a patch for 1.4.13 or will this make it into
1.4.14?
