do you know or have heard of any device which can block certain calls coming to our gateway and allow only calls starting with particular numbers for e.g it should block calls starting from 2,5,6 and allow all calls starting from 3,4,7,9 etc, all this should happen before the call is passed on to the quintum gateway.
We are using the below config to connect pstn calls to our quintum
Calls come to cellsocket and then from cellsocket we have connected a RJ-11 cable to the PSTN ports of the quintum.
I need some more detail about ur network and lam pattern under pstn trunk group.
1. Is ur network include a Gatekeeper?
2. What is ur current lam pattern and exactly what you want to do? I appreaciate if you can just copy the current pattern and paste it here and then describle ur requirement.
