[Asterisk-Users] limit incoming calls to sip extens

[Ryan Courtnage]

Hi all,

I've been using the following method to limit calls to sip clients to 1:

exten => 200,1,SetGroup(200)
exten => 200,2,CheckGroup(1)
exten => 200,3,Dial(SIP/200)
exten => 200,103,Busy

This works fine for a single extension.  

However, I also need to dial groups of sip clients.  It appears that SetGroup can only be used once per channel.

This (useless) example would not work properly (group 200 will always have a count of zero):

exten => 700,1,SetGroup(200)
exten => 700,2,CheckGroup(1)  ; this will never jump to 103
exten => 700,3,SetGroup(201) 
exten => 700,4,CheckGroup(1)
exten => 700,5,Dial(SIP/200&SIP/201)
exten => 700,103,Busy      
exten => 700,105,Busy


Does anyone have any suggestions on how to accomplish this?

Thanks
Ryan
