Asterisk PRI Span Debugging
Please follow these steps when faced with dead span:
Record the stdout to file for each command.
1. wanrouter status
Check that wanpipe status is Connected
2. wanpipemon -i w1g1 -c Ta
Check the physical T1/E1 Alarms
3. Run: ifconfig
Make sure that tx/rx counters are incrementing.
4. tail -f -n 100 /var/log/messages
Check for any wanpipe errors in messages
5. wanpipemon -i w1g1 -c trd
Run a dchan trace and check that you are seeing incoming and outgoing traffic.
(Note: this option only works with TDMV_DCHAN option enabled, which should be enabled by default.)
6. From asterisk CLI
run: pri show span 1
Check that spans are UP and Active.
run: pri intense debug span 1
Confirm that in/out messages match the trace messages in step 5: from wanpipemon dchan trace.
