Good morning,
This is the scenario: User 1 (PSTN) calls freeSWITCH (DID). Calls goes through PSTN Gateway (1) to freeSWITCH application server (AS) (2).
AS does some logic and transfers call (or forward) out of Voip provider network to another PSTN number User2.


This is call bridge


    UA1     (PSTN) -                                 ->  UA2 (PSTN)
              -                                            -
                -  (1)                                   -  (4)
                  ->         PSTN Gateway->
                            -                        -
                       (2) -                        - (3)
                          -> FreeSWITCH ->


This is what I want to acomplish
                                    (4)  
    UA1     (PSTN) ------------------------------- ->  UA2 (PSTN)
                    -                                    
                       -   (1)                              
                        ->  PSTN Gateway->
                             -                        -
                       (2)  -                        - (3)
                            -> FreeSWITCH ->


1. Can it be implemented in FreeSWITCH?
2. Does anybody know Voip providers which support out of network call transfer/forwarding to PSTN?

TIA

Hi there,

Are you wanting to keep the SIP signaling in FreeSWITCH (SIP re
INVITE) and only pass back the media to the network, or pass back
signaling also (SIP REFER)?

I know several suppliers who support SIP re INVITE but none that
support SIP REFER.

Yes, I need SIP-REFER (pass back media and signaling to PSTN). I am pretty sure it is doable because voxeo offers this
option for their Voice XML customers but I am not interested in a hosted solution at the time - it is quite expensive. As far as I understood, Voip provider MUST have pstn call transfer feature enabled by telecom provider (AT&T for example) and this should work fine with SIP.

Actually, this is what I need

Will it work with PSTN? Can I redirect incoming PSTN call to another PSTN number?

Are your calls coming in on TDM or SIP trunks? Are your calls answered
by FreeSWITCH before you need to redirect them?

A call is coming on SIP trunk. From PSTN.  I does not need to be answered, actually - I need to do some logic before redirecting call but I can answer call as well It won't break the app logic.

I don't know of any sip carriers who will let you do refer. you will need to find a carrier who supports it. FreeSWITCH will have no problem sending it but I doubt you will find a carrier who will let you do it easily.
