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. -- Regards, Abdul Basit On Tue, Jul 12, 2011 at 2:42 PM, Yo - <yoherman at gmail.com> wrote: > as my experience.
