asterisk users - Aug 2004 - limit incoming calls to sip extens

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

I only wish we could do this with queues so that Dynamic agent queues
would only pass 1 call to each agent. There are times when * tries to
send an additional call to an agent while they are on the phone which
results in the call-waiting 'beep' notification etc.
