Chapter 4: Troubleshooting

1. Check the method being used by attempting the following in your line

context:

_X.,1,NoOp(My DID matches as ${EXTEN})

Then type reload in the Asterisk console and call in. You should see

the DID come in on your T1/E1 line.

My D Channel seems to go up and down.

Check to be sure you have set your timing parameters correctly. Also,

check the common causes of problems for a T1. See the Common Fixes

for all cards, page 58.

I have trouble dialing out. It seems that one type of dialing works

(local, long distance, international), but another does not.

Check your

pridialplan variable and verify that you are dialing using the

method your telco is expecting.

I am having trouble receiving DID information over E&M.

Try the other types of E&M (featd, featb, etc.) to match the method your

telco is using to stream information.
