Hello,
It would be a great help if someone can guide me.
1. I would like to first receive a call, perform certain validations. (Able to do this via mod_managed application that handles call from dialplan).
That should not be a problem, I don't know your requirements so can't provide a full answer.
2. Now, I would like to dial out to a PSTN number so that received call is connected to this new outbound number.
This can be done and is called hairpinning.
How can this be done? Do I use Originate from within my .NET (mod_managed) code?
Yes, you would be bridging the two legs like any normal call. Instead of going to an endpoint you're going back out over the PSTN.
Do I get charged for both incoming and outbound call until the entire session ends? Is there a way to receive call, validate and then sort of transfer and then terminate the received call so I do not get charged for both?
That would depend on your provider but most likely yes. As for terminating one end after validation that is not going to happen. A leg terminates to you on an agreed fee schedule. No carrier that I know of supports that. Now if you kept everything SIP... you could do a transfer after the validation. Anthony C.
