Never mind I found a way to resolve the problem.

i: Ignore call forward requests from queue members and do nothing when they are requested.

{{exten => s,10,Queue($QUEUE,$OPTIONStTi,,,$TIME)}}

> Given I have a queue with 1 member: Alice (SIP/alice)
> Given Alice's phone has a forward (SIP native) to the 444 extension, and the 444 extension isn't defined in the dialplan
> When Bob calls the queue
> Then asterisk get stuck in what seems to be an infinite loop, consuming a lot of CPU time, and rapidly consuming (in the matter of seconds) all the available memory in the system, until the kernel OOM killer terminate the process
> In my example, I used the following queues.conf:
> {code}
> [sales]
> strategy = ringall
> member => SIP/alice
> {code}
> And the following extensions.conf:
> {code}
> [default]
> exten = 101,1,NoOp()
> same  =   n,Queue(sales)
> same  =   n,Hangup()
> {code}
> When Alice's phone receives a SIP INVITE from asterisk, since it has an unconditional forward enabled, it respond with a "302 Moved Temporarily" with the header "Contact: <sip:444 at 10.34.1.11>".
> I've attached the interesting part of the log.
> Thank you
