Alright. I got the documents and now I am able to route the incoming calls (PSTN) to IP.
but now the problem is:
When the caller Hang up the call, my PSTN Line remains busy.
even the LIGHT at PSTN port is not blinked which means (As I think) Quintum is not using the Line. but line remains busy until I plug out the cable from PSTN port and plug back in.
The IP Address where I route the calls doesnt have any connectivity with the Line either.
so who is holding my line? I am sure it is quintum. any help will be highly appreciated.
