[asterisk-users] Single BLF for ALL trunks in use

[Jim & Karen Ostrosky]

Hi, first time poster.  I've searched, but find very little on this topic.

My church has only 2 incoming phone lines (copper), being serviced by 
Digum TDM400 card.  The existng phone system (being replaced) was a key 
system, easy for users to tell both lines were in use.  We have chosen 
Polycom 430 phones for the new system, and from what I can tell, I'm 
only going to have a single light to work with, via the directory & 
"buddy watch" method.  So far, so good - I can watch a *single* Zap channel.

What I'd really like to do - for now - is to take the hint, which is 
currently assigned to the specific Zap channel, and somehow have it 
indicate that *all* of the available trunks are in use (all 2 of them 
right now).    This so the people using the system know that both 
outgoing lines are in use, please wait to make a call.

I've seen syntax like exten => 1234,hint,(Zap/1&Zap/2), but I don't 
understand the & part (does it mean any of?).   Is there some similar 
syntax that means all of?  Or, is there a way to synthesize a dummy 
extension hint out of the individual channel hints?   Or.... is what i'm 
asking not feasible?   I hope this is clear...

thanks
