[asterisk-dev] $200 reward for pickup patch for 1.8.4.4

[Alistair Cunningham]

Alec,

You're the first to reply to this. The problem is occasional Asterisk 
crashes when a FastAGI daemon does:

EXEC 
Dial(Local/<phone1>@enswitch-pickup&Local/<phone2>@enswitch-pickup&Local/<phone3>@enswitch-pickup&...)

In some cases, customers have 20 or more pickup destinations configured 
at once. We then have:

[enswitch-pickup]
exten => _[0-9*#]!, 1, PickupChan(Local/${EXTEN}@enswitch-phone)

[enswitch-phone]
exten => _[0-9*#]!, 1, GotoIf($[ "${ENSWITCH-MUSIC}" = "" ]?3)
exten => _[0-9*#]!, 2, SetMusicOnHold(${ENSWITCH-MUSIC})
exten => _[0-9*#]!, 3, 
Dial(SIP/${EXTEN}@${ENSWITCH-PHONE-DOMAIN},3600,${ENSWITCH-PHONE-OPTS})

In older version of the code, I seem to remember trying simpler schemes 
(such as having the FastAGI do Pickup() on enswitch-phone directly) that 
didn't work. I don't remember the details as it was a long time ago - 
perhaps some Asterisk bug prevented it?

In addition, you should know that:

1. Sometimes there are many phones (up to 20) ringing at once due to 
large hunt groups.

2. This is on a large multi-tenant hosted PBX system, with hundreds of 
calls going at once.

Debugging this is not for the faint-hearted!
