Can someone suggest me wholesale and cheaper provider than Vitelity but offering similar service?

In/Out bound both USA.

Thank you.

AFAIK, most (all ?) providers wont accept the transfer.
They are not allowed to change the rate of the call from the caller perspective after the call was initiated.
Imagine you transfer the call to an Iridium number...

Hi,

i am wondering what will happen if you send a SIP REFER (transfer) after validating leg-a without actually answering the call; will it still cost you 2 * 1.44

:/

I am currently looking at Vitelity. They have 1.44 cents per minute. They do charge for incoming/outgoing both.

I am not literally dialing out to a phone. I want to dial a mobile number or any other US number for that matter.

Here is what I intent to do:
1. A US phone dials to Vitelity number -- comes to my FS box
2. I validate few things
3. Dial another US number and connect received call to that one

So as you said I will be charged 2 * 1.44 (since I can't terminate the arrived call after validation).

Is there any other way to the sequence I have specified above?

Are there providers similar to Vitelity but cheaper (with relatively same features)?

Thank you.

That should not be a problem, I don't know your requirements so can't
provide a full answer.

This can be done and is called hairpinning.

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.

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.
