SIP to PSTN Call Forwarding, with individual forward number per SIP account

We are looking for a provider who is able to provide us this kind of functionnality:
We are using a server who is able to make SIP call only
We would have several SIP account at this provider
For each SIP account, we could set an auto-callforward to a specific PSTN number

We have found providers giving us the possibility to set a Call Forward when the DID is called, but this call forward doesn't apply to SIP calls.

Do you have any provider who could let us do that?  Otherwise, do you see any other solution to our problem?

Your help is greatly appreciated!

What server are you using in your offices / data center ?

If you are doing server to server SIP calls, my Asterisk to your Call manager for example then the carrier really is not part of the conversation and you must forward the calls yourself.  Otherwise, a number of carriers offer the ability to deliver to a Cell or PSTN number, although usually this is in case of connectivity failure.

The server who is doing SIP call is Pexip.   Once the call is established, we order it to send digits to identify the conference code of the user.   The number that we call is a regular phone bridge (PSTN) because it doesn't allow us to call it thru SIP.
Not familiar with this product.  

But a very quick look at the web page implies full SIP support, get a trunk from a provider and connect it.

I'm well aware of what Pexip can do and can't do.  That's why i asked this question over here:

Is there any method to setup an autoforward to a PSTN when a call is received on SIP?  And is it possible to setup multiple individual forwards?

Your solution to Asterisk is vague.  I'm aware of the existance of Asterisk, but i don't know what's it's limits and before investing tons of time on that, i want to be sure that it fit for the job.  And better, if there's a provider somewhere on the planet who offer this kind of service, we would certainly buy it.

Is it possible to close a question, give the point to the person who helped, but not mark it as an answer?

The question was simple.   I've asked for a solution giving me the opportunity to redirect calls automatically from SIP to PSTN.

SIP call made to sip:frenchaccount@ has to be forwarded to PSTN 1-800-123-4001
SIP call made to sip:englishaccount@ has to be forwarded to PSTN 1-800-123-4002
SIP call made to sip:spanishaccount@ has to be forwarded to PSTN 1-800-123-4003

I thought that an existing service or software could let me do that.
I know about "Asterisk", but it's involve a lot of time to know it deeply, and without any tips on how to do that with it, i don't see this as an answer.

i've got to close this question.  I'll have to test Asterisk by myself and see what its capable of because it was a bit vague.
