[Asterisk-Users] IAXy playing dead again

[Wilson Pickett]

It's happened before, cleared up and now it happened again.

The IAXy, working for a total of about 6 months. 

Symptoms:

Registered with asterisk and even receives calls (the LED shows it's
ringing) but phones connected to it are dead.

Same phones work connected directly to the phone line. 
Cable swapped out, no difference.
Endless re-provision (with normal looking output)  and power recycling.

This really looks like a dead FXS - except - this has happened before
and it came back.

Comments? Suggestions?

As a TV repairman once told me, "The most obscene word in technology
is 'Intermittent' "
