[Asterisk-Users] analog phone connects to zaptel fxoks is beeping

[Michael Jia]

Hi,

I have a analog phone connect to a WCTDM card.
It used to work fine. Now recently, after several conf change and power
restart,
it stops working.
Whenever I pickup the phone, instead of hearing the dial tone, I hear a
busing beeping
tone, like a machine gun is firing. :) However, from asterisk console, I do
see a a
OffHook/OnHook message, but whatever I dial in the phone keypad seems not
recognized
by asterisk, and it doesn't print out any messages.

What could cause the problem? Any clues?
Highly appreciate your help.

Michael
