Hello!
I am busy, did not read ur problem in detail. but if u use tpad, it is free.
Just download their softfone. get their phone no and start receiving calls from pakistan at local call rate. U can configure it in ATA also if u have broadband (DSL/Cable) access. They donot charge for incomming calls or DID numbers, just ur family will pay for local call to DID number, or u will have to pay for out call (if u will use it). Go to
www.tpad.com and see.
You may have brain in ur family ID.
