It may be a problem with the ATA unit. Have you tried unplugging it, waiting a bit, and then replugging it?
We do have voice, but we haven’t had a working phone for over 2 months. The phone now gives a message that our device is not recognised by our server despite having worked for outgoing calls for an hour or so.
Our phone will not ring, and we have tried several different phones.
It's been a while since we last heard from you, so we will close this thread. If you still have concerns, please start a new thread and include a detailed explanation so we can better assist you.
