I'm not sure if this is a problem with our polycom 501 phones or with a
setting in asterisk.
When you set the forward option on the phone and have it point to an
outside number (a cell phone) we see the following problem... The call
does forward, but while its doing so and while its ringing,
Hi,
today with my asterisk during a call I had a very strange noise, it was the
typical noise that you can have when your device uses a bad power supply.
I change phone and I had the same behavior after I while I tried again and
the noise was disappeared.
What can I check?
