I am very new to the world of VOIP. Recently I purchased a Uniden UIP1868 VOIP phone. Unlike the 1868P which is a packet8 phone, or the 1868V which is hard configured for Vonage, the 1868 was said to be compatible with most services providers. I know enough about home networks to connect the phone to my router which is fed by a Motorola cable modem. Working with my service provider (VYL Media) I was able to get the phone to register, and get a dial tone. But now I'm stuck. I cannot make calls (most result in a fast busy, or a "Your call cannot be completed as dialed) or receive calls (when I use my cell phone to call my VOIP line, the call goes right to voice mail.) My service provider thinks that the problem may have something to do with the 1868 not having a stun server. The SIP setup asks for a SIP server, an outbound proxy server, and a registration server, but no stun server.
Does anyone know if there is any way around this limitation? Any help would be very welcome. Thanks, Mike.
