No Audio

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



have you tested with dahdi_monitor on the active channel?

See if what audio side (Rx or Tx) you are getting. This is CIC miss-match
issue.
dahdi_monitor might help you figuring out the next CIC that has audio
channel. see all one by one.

Also do it step by step. Stop all E1s as suggested and then start up in
steps. Monitor CIC with dahdi_monitor.
