Can you plug a phone directly into the ATA with nothing else? I understand Videotron's ATA works good but it's still a valid test.qwerty wrote:Thanks Laurent, yes I do have the same noise when I call voicemail. In fact I hear it even during dial tone... My home is a recent built and I wired my telephone myself with shielded CAT5E for telephone and CAT6 for networking (both as a star network). Cable length or age of cable is not a factor. Both my videotron phone modem and may FPL VOIP modem are located in the basement so the setup (cable length, jack, etc...) is the same during my tests. Clear line Videotron, faint buzzing on FPL. Everything else is perfect, I am sure the solution is hidden in the settings.
Which pair did you use for phone in your CAT5 cables? Central pair, blue/whiteblue?
Your problem appears to be electric related, not "internet-software-codec" related. Is the ATA close to the modem? If so, move it away. Actually, try to move the ATA and it's cables at least 1 meter away from everything electric or electronic. Make sure no 120 volts electrical cable run near the telephone wire, or near the ATA. You could also grab an extension cord, and go get some juice from another room and plug your ATA (and only your ATA) in it.
These wonderful plastic electronic devices are incredibly NOT tolerant for interferences, and most of them spit out a large quantity of it themselves! I've had modem issues when they were too close to a router, for example. Use your cordless phone, call something where you can have silence, like your cellphone perhaps, and then while listening, move stuff around a feet or two.
You might have interferences coming from the supply cables, from the network cables, from the air (emission from another device).
You could also have ground loop problems, and this we can tell if you remove the house cabling from the ATA, and plug your cordless base station right in it.
Oh and the cordless base station could also be picking up interferences. If all else fail, try another phone just to prove me wrong
