[Asterisk-Users] TDM400P FXO channel hookstate always "Offhook" & outbound digits sent before provider dialtone

[Stephen Joyce]

I have an Asterisk at Home 1.3 server (Asterisk 1.0.9) and recently added a
TDM400P with (1) FXO card on port 4. Inbound calls are always successful
but outbound calls fail 75% of the time with intercept messages from my
dial tone provider that include "we're sorry, your call did not go
through", and "we're sorry, when placing a local call it is now
necessary to dial an area code and the 7-digit number".

I have connected a test set in monitor mode to the phone line to listen
to what's being sent out the line by the Zap channel and 10 digits are
sent but the first digit is usually sent only as I hear the dial tone
being drawn from the line, so it appears that it's sent before the
provider is ready to receive it. I can't find any sort of setting that
would allow me to manually configure a dialing delay on the line, but I
suspect this would provide a band-aid.

When looking at the Asterisk CLI, I see that the correct number is being
dialed by my dial plan. I am calling from SIP extension 1100 and calling
770-555-1234, which is a local 10-digit phone number.
-- Executing Dial("SIP/1100-9adc", "ZAP/g0/7705551234") in new stack
-- Called g0/7705551234
-- Zap/4-1 answered SIP/1100-9adc

The status of the channel is "Offhook" regardless of whether or not the
phone line is actually Offhook or completely idle. I'm assuming that
when the line seems idle, it should show as Onhook.
