[asterisk-users] No incoming audio on Dahdi channels (TDM410P)
A previous issue has popped up and once again I'm out of ideas. During
the evenings it seems that the TDM channels will spike (dahdi_monitor)
and will refuse to listen for audio of any type, this includes DTMF.
The only resolution I know of is to stop Asterisk and restart the
dahdi service, but that's not a solution.
All channels look like this, even the FXS.
[root at asterisk Hardware]# dahdi_monitor 1 -vv
Visual Audio Levels.
--------------------
Use chan_dahdi.conf file to adjust the gains if needed.
( # = Audio Level * = Max Audio Hit )
<----------------(RX <----------------(TX
###################################*
Rx: 30076 (30076) Tx: 0 ( 0)
I've stopped every service except SSH and networking (according to
service --status-all) and nothing has changed.

Is that normal? Here's the output of dahdi_diag 1:

No idea what any of that means or how it's relevant.

[asterisk-users] Same Problem with AEX808E Re: No incoming audio on Dahdi channels (TDM410P)
Hello, i got the same problem with a Digium Card an AEX808E, with dahdi
linux 2.2.0 dahdi tools 2.2.0 and asterisk 1.6.1.4
i did update to the latest of everything hoping it will fix the problem,
but it still remains.
i got:
Aug 14 02:29:16 ctg01 kernel: [ 9257.702038] wctdm24xxp0: Missed
interrupt. Increasing latency to 4 ms in order to compensate.
Aug 14 09:06:00 ctg01 kernel: [38791.679058] Unable to set SW Companding
on channel 0 (reason 4)
and there is audio in one way.
Not a problem with the network, i use simple record and playback to test
the card.
in the begining it works but some time after the problem appears and the
only solution is to stop asterisk, restart dahdi and start asterisk, of
course not an enterprise solution.
Has somebody found a solution to this problem ?
i am really dissapointed with latest pieces of digium hardware, maybe is
time to test another ones....
