Hello, I just received and setup my Obi110. I have a SIP service on SP1 (FreePhoneline) and Google voice on SP2. I had no trouble setting up google voice and it is working perfectly. My SIP account on SP1 is giving me trouble. I can receive calls no problem, but although I can call **9 222 222 222 and connect, when I try to call out any local number I get a strange tone and a male voice telling me "The number you dialed was rejected by the service provider error number 500"
Any ideas? I have a Linksys wrt54gl with DD-WRT v24-sp2 (10/10/09) voip firmware. I have the milkfish section disabled. I've heard that sometimes you have to disable the SIP ALG setting but DD-WRT doesn't seem to have this setting.
