I am new to using SvSip and I cannot get it to work properly. I configured the router to allow the calls. The DS connects to the wireless signal. SvSIP loads and connects to the access point. I see the keypad, then I type in the number I want to call. I put the 00 before the number, then the country code 1 for the US, then the number and hit dial, immediately I get the message: "Invalid URL sip:0018005551212@(null) Invalid URL sip:0018005551212@(null) Does anyone know how to fix this?
