In my Grandstream, I have fm.grandstream.com/gs for both firmware and provisioning.

I read in another thread about how a fw was pushed that wasn't supposed to be yet but how was it pushed if the ATA has fm.grandstream.com/gs ?

I'm not sure if all the settings are correct in my GS as everything seems to be default. Is that the way it's supposed to be? I get sporadic issues on calls such as when dialing an automated system, the touch tones not working or when I get a voice mail the phone disconnects. Actually it's not very often this happens but just makes me wonder if my GS is supposed to get updated every now and then.
