PSTN and SIP switch device

Posted:Thu 11 of Feb, 2010 (16:52 UTC)
Dear All, I have a PSTN and SIP line. I am looking for a simple device where I can make direct calls through PSTN and when I need to make SIP calls I call a prefix number like or 9 and that call can be routed to SIP line. I got the Draytek Vigor 2820VN router but do not offer such functionality.
Please help
