I can confirm that when INVITEs are fired at Asterisk using sipsak, the issue occurs.

Wait(0.1) in the dialplan does not mitigate this issue.

Attached my dialplan and CLI output.

> When we fired several calls trough a SIP trunk simultaneously, the GROUP_COUNT and the GROUP_MATCH_COUNT could return the same number of calls on that trunk.
> You can found more info on the issue_full.txt (full log extract) and the issue_dialplan files.
> [Edit by Rusty - You can reproduce easily with the following dialplan]
> {noformat}
> [from-internal]
> exten = 101,1,Dial(Local/s at group-dial&Local/s at group-dial)
> [group-dial]
> exten = s,1,NoOp(Group count is: ${GROUP_COUNT(1)} )
> same = n,Set(GROUP()=1)
> same = n,Wait(45)
> same = n,Hangup()
> {noformat}
> Making several calls from one or two phones to 101 will result in the GROUP_COUNT occasionally being reported as the same (for the same group) for a pair of channels.
