Hi Guys,

NEC sl2100, many phones have a weird random incoming call but only noises when pick up the call.
It started to be happening this week, no problem before for a year.

1. Random phone ringing, ringing sound as internal phone
2. after pick up the call, there are only noises. Listening closely to noise, it sounds like a busy call but with a lot of noises.
3. I'm sure that we didn't do any updates on it.
4. Already reboot the machine, but still happening
5. I did call testing to our phone external lines, all lines are working.

Did this happen to anyone before?

Thanks
Pong
