I’m running Asterisk-220.127.116.11 on a FreeBSD-7.0 server. I have a couple of GS IP phones sprinkled around my LAN. All has worked well for many months but suddenly I noticed I could no longer login to my voicemail boxes. I am constantly getting a “Login Incorrect” message. So I slowed down and made sure I was entering the right key strokes on the phone, which I was. I then watched the CLI screen for any clues as to what might be happening and sure enough there was evidence of the problem. When I was entering 2000 on the phone, CLI screen would show that I was entering 22000 or 20000. The password digits were also getting some kind of double stroke or echo happening. I checked and rechecked that I was only entering the correct key strokes and I was. Sometimes only one of the entries was incorrect but always one of them ended up with an extra digit in it.
This is strange because I have used this system for a long time now. The firmware on the phones is set to update automatically and I did notice a bit of a problem with one of them a few weeks ago but that settled down.
Update - I just noticed that it’s really going bonkers now. I entered 2000 and the CLI screen shows it received 2000000. Do I suddenly have some kind of echo issue here?
