I have an S500 that was given to me by a friend and I was having problems setting it up. It wasn’t until I blocked rs.sangoma.net on my firewall that it started to behave.
I was then able to complete the setup and use the phone, but as soon as I remove the DNS block on rs.sangoma.net it goes back into the freezing behavior and starts a boot loop.
Is this phone simply broken or has Sangoma crippled it?
