[Asterisk-Users] PRI Call Redirection / Transfers

2004-08-03 Thread John Harragin
I have a PRI comming into each of 2 buildings. How do I redirect an incomming 
call on PRI_A of particular DIDs to arrive at PRI_B instead?

Thanks,

John

If you want complete control from the Asterisk side you'd probably need a 2B
transfer facility enabled on the PRI to allow Asterisk to tell the central
office to shunt the call elsewhere. However, that functionality isn't in
Asterisk yet:

Under what circumstances? If the first T1 is down, for example?

   I have a PRI comming into each of 2 buildings. How do I
   redirect an incomming call on PRI_A of particular DIDs to
   arrive at PRI_B instead?
  

Not a real standard way of doing it in my experience.
Each switch type seems to have a different mechanism.  For instance the 
5E has a feature called TBCT (two b channel transfer) which is 
essentially like a supervised transfer or if you just reject the setup 
message on a new call with a cause code 43 (if i remember correctly) it 
will route the call to an alternate trunk group--this is called DTO 
(direct terminal overflow).

Just unplugging the cable or throwing the t1/e1 into a loop does not 
seem to keep 5e's from routing calls to a trunk.  The individual bearer 
channels must be put in maintenance busy to keep calls from getting sent 
to them first.  If this capability is not available on your end it often 
requires a call to the carrier to do it for you.

I am not sure if any of these capabilities exist in *. Others will have
to answer that but, I have seen no mention of them in the wiki.

It might be nice to have say the 'restart gracefully' command put idle b 
channels into 'maintenance busy' to keep new calls from coming into them 
  and to also do it to them when existing calls drop off.

Just my two cents worth.


Rick
