Hi,

I have 4 SIP Peers for outgoing calls ... [outgoing1], [outgoing2], [outgoing3],  [outgoing4]....and my SIP Service provider provies Multiple Calls from a single
account......which means I can make more than 3 calls from each of these peers...
but I want to make a single call at a time from these peers....
I tried CHANISAVAIL() but it doesnt work because SIP Provider supports multiple
calls from single account.....
I want something like "ACD" , if [outgoing1] is busy then dialout from [outgoing2]
if [outgoing2] is busy then try [outgoing3] . . .. 

thanks....
