Yes, I need SIP-REFER (pass back media and signaling to PSTN). I am pretty sure it is doable because voxeo offers this<br>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.<br>

Hi there,<br>
<br>
Are you wanting to keep the SIP signaling in FreeSWITCH (SIP re<br>
INVITE) and only pass back the media to the network, or pass back<br>
signaling also (SIP REFER)?<br>
<br>
I know several suppliers who support SIP re INVITE but none that<br>
support SIP REFER.<br>
