asterisk users - Sep 2004 - SetGroup Limitation!!!

Hi all,

 

I am just scratching my head trying to work out a way to use SetGroup to
check busy status on a sip to sip call.

 

The complication is that one call can't be in two groups so I have got no
way of setting busy status on both the calling and called party.

 

Has anyone got a way around this.

 

Thanks

 

Daniel

Yes, a channel (not a call) can be in two groups, the trick is that they 
have to be in different categories. So you can do:

exten => 1000,1,SetGroup(${CALLERIDNUM}@outgoing)
exten => 1000,2,SetGroup(${EXTEN}@incoming)

This makes this particular channel be in both of these groups. However, 
you will not be able to use GetGroup() to do your limit checking (unlike 
what the wiki page says, I should rewrite that page one of these days), 
you must use GetGroupCount, specifying the exact groups you want to 
check, and then branching based on the GROUPCOUNT variable with GotoIf.

We have this working here just fine, it allows us to have intra-PBX 
calls handled differently than inter-PBX calls.
