[asterisk-biz] forwarding

[Andor Czafik (Akakiko)]

Hi,

I am new in this list, and my english is not so good, so sorry for my 
english.
We want to change our external callcenter to new, internal callcenter, 
but first time, we need to work with external parallel.
We will connect to our telephone provider with sip trunk, and the X 
percentageof incoming calls will be forwarded to external callcenter, 
and 100-X percentage will go to our queue of agents.
My question is, how can i make this forwarding rule, the percentage is 
allways changing.
My idea, please tell me, while is a stupid idea:
Ill  make 11 normal sip extensions, 1 queue,  and ill make 10 sip 
trunks, and with 10 sip trunks i will connect to 10 sip extensions.
 From this 10 trunks, X percentage is ringing on 1 sip extension, and 
this extension goes to external callcenter. And the remains trunks goes 
to our queue of agents.
Its working now, but only with two asterisk server, because i can not 
connect to localhost with sip trunks. And this is my second question, 
how can i connect to localhost sip extension (loopback connections with sip)
I use asterisk with destar.
Thanks for helping
Andor
