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.

ruffle:

I'm not 100% sure of it, but I think the fix for the half-ring also fixed
the queue problem you mentioned (assuming you still have the same
forwarding rule applied to SIP/116 as you do in your first test). I tried
to reproduce and could not successfully. If it is still a problem, could
you post your sample dialplan that you use for testing queues? Thanks.
