Freddi Hansen commented on ASTERISK-20918:
------------------------------------------

I have tried forking 10 calls via local channel to sip-phones and get the same. ( on 1.8.20 )
If I take a wireshark of all calls then I can see that the number of CANCEL's sent is ok but some of the calls get multiple CANCEL's while other don't get any.

This setup has another sideeffect. If I answer one of the 10 phones dialed i parallel then it will be disconnected in 10-20% of calls. 

I am not an "Asterisk locking wizard" that can solve this I just wanted to confirm that I se the same issue.

> When Asterisk does a Dial() to multiple destinations and one of those destinations answers, it only sends a CANCEL to some, but not all, of the other destinations.
> Attached is an Asterisk trace showing a call an AGI which implements a hunt group.
> On line 3804 it Dial()s the destinations, which launches a new AGI for each destination.
> Each destination AGI then dials the phone.
> You can see that phone 6326821 is sent an INVITE at line 10048.
> At line 46774 phone 6326838 answers the call.
> Then CANCELs are sent to many phones, but not to phone 6326821.
> Thanks.
