[Serusers] forwarding to PSTN

Hello everyone, My phone system has a call pick-up functionality tht I would like to implement in my voip system. We have couple of phones, and once the phone rings anyone in the office can pick up that call by pressing *74. I am trying to do the same thing with ser. Can anyone help me with the uri check please? This is what I have: route[1] { # Route to PSTN Gateways(s) if (uri=~"^sip:9[0-9]*@sip_gateway.com") { ## This assumes that the caller is log("Forwarding to PSTN\n"); ## registered in our realm strip(1); t_relay_to_udp( "sip_gateway.com", "5060" ); break; }; if (uri=~"^sip:*74@ sip_gateway.com") { ## This assumes that the caller is log("Picking up a Call on PSTN\n"); ## registered in our realm t_relay_to_udp( "sip_gateway.com", "5060" ); break; }; } I am getting 404 error on my grandstream phone. I think there is a problem with the "*" symbol. I guess i am using it wrong. How do I send * followed by 74 to my gateway? thanks, Srbo Cvetkovic | CityNet, Inc. srbo(a)city-net.com | Pittsburgh, PA voice: 412.481.5406 | fax: 412.431.1315
