[Asterisk-Users] A TDM issue..

[chouck]

Oooh.. That makes sense now..  I have only used fxo for a pots line and 
would issue dial like so:

exten=blah,1,Dial(ZAP/1/blah)

But I never really thought about just a simple dial without a number.. so 
essentially the card will just pick up the channel and bridge them together?

Thanks alot everyone,

-Chad
