[asterisk-users] Disconnect after 12 seconds w/Cisco 303g Phones

[Todd Routhier]

So, I have this customer with a completely bizarr issue.

She reports that on either of her shiny new Cisco 303g phone, calls are
disconnected at exactly 12 seconds after taking caller off hold.

To be clearer:
-Answers incoming call, can talk forever no problem.
-Places caller on hold and can leave them there forever.
-Picks up call and 12 seconds later, call disconnects.

I am going to turn on some debug logs on our Asterisk box a bit later and
watch the CLI as this happens to see if I can capture anything interesting
but wanted to check with the list in the meantime.

Other older Linksys/Cisco phone with slightly different model numbers don't
have this issue and have worked phone for many moons :-)

Never ran into this before, really puzzled. Google, searching the list
archives etc, weren't any help.

I am thinking this has to be the phones or some settings within. Two
phones, same model on same network are doing the same thing. No way to
easily get customer a different model phone to test with so I will have to
test with softphones to see if removing the phones from the equation
resolves the issue.

Any help would be appreciated, thanks.
