[asterisk-users] PRI Callerid Passthrough

[Rizwan H Qureshi]

Thanks AJ and David,
We were actually using GSM gateways by setting busy forward number on the
SIMs and just giving busy signal on every incoming call, telco took care of
the forwarding and the line was free within seconds. Now we need to scale
up the setup but GSM gateways a very very expensive if we want to scale
upto a 1000 DIDs, which means thousand SIMs and a gateway/gateways big
enough.
