I'm planning to switch to VOIPo when my contract with my current provider is close to expiration. My current VoIP device is the Grandstream 502, which, I was informed, is the device which VOIPo now distributes. My experience with it has not been nearly as good with other devices, including the Innomedia device left over from SunRocket and used successfully for over a year with VOIP.com. My current provider now distributes SIP credentials, but the Innomedia device does not seem kindly disposed to that provider. Usually, I can maintain registration for a few minutes only. The provider recommends a 4-hour registration time, but the longest that I can set up on this device is about 3 hours.

Has anyone used an Innomedia device with VOIPo services? If so, what is a reasonable registration time to use?

Thanks.
