Static on S505 Phones

well after several attempts at resolving this problem, we are still getting this ‘static’ sound on these phones in reception. Here’s a rundown of everything we’ve attempted:

  1. Updated to the latest firmware (.74). Rebooted.
  2. Replaced POE switch
  3. Removed phones from POE ports and attached separate Power cable.
  4. New Ethernet Cables.

Can’t think of anything else to try.

This ‘static’ is not occurring just when we pick up the phone, The sound can be heard during the ring as well which leads us to believe that perhaps this is a memory issue or something because i also recall that during initial configuration of these devices, after several template modifications, we would have the same problem and only a reboot would solve the issue.

Its odd this only happens in the reception area and also wondering if that is because they get a large volume of calls compared to the other phones?

Any ideas please… this is really causing some serious trust/confidence/credibility issues with my customer.

EDIT: our case is somewhat different than this one as the STATIC in our case prevents us from hearing/talking altogether. Sangoma S505 Phone - When making a call the sound skips during dialing and ringing
