Full Version: 100 calling

I work with tech support for a VOIP system, and we seem to be having an issue with a few phones. They will get a 100 calling them and it will just ring and ring and ring. If they pick it up no one is there. It will never leave a voicemail due to the face that it doesn't go through the phone server. When we go into the call log on phone it gives the phones IP address @ the router. With the Caller ID being 100, so it seems almost like it's coming locally. Any idea or fixes?

Thanks

Hi Crow2882,

1. Please disable the Allow IP Call in the webpage.
(Webpage->Features->General Information->Allow IP Call, disable it)

2. Limit the IP address in your voice switch and can keep this IP address away.
