Re: Configuring OpenVOX A400P issues

[Kaya Saman <kayasaman@xxxxxxxxx>]

Thanks Vladimir for the response and apologies for my extremely late one! This week was quite crazy!!

I have just upgraded my server to FreePBX to take advantage of an "up-to-date" system.

I migrated the original config over with a few set changes.

Kaya,

I do not have a definitive answer for you, but here are several things I noticed.

1. fxols=1  --  I would definitely try fxoks instead
   

I altered this in /etc/dahdi/system.conf:

# cat system.conf
# Autogenerated by /usr/sbin/dahdi_genconf on Sat May 19 20:22:49 2012
# If you edit this file and execute /usr/sbin/dahdi_genconf again,
# your manual changes will be LOST.
# Dahdi Configuration File
#
# This file is parsed by the Dahdi Configurator, dahdi_cfg

# Span 1: WCTDM/4 "Wildcard TDM400P REV E/F Board 5" (MASTER)
fxoks=1
echocanceller=mg2,1
fxsks=2
echocanceller=mg2,2
# channel 3, WCTDM/4/2, no module.
# channel 4, WCTDM/4/3, no module.

# Global data

loadzone    = uk
defaultzone    = uk

1. ............
   fxsls=2  --  I am not sure about your provider but I would try fxsks instead

I think the above took care of that too.....

1. [May 13 13:15:31] WARNING[3624] chan_dahdi.c: CallerID feed failed: No such file or directory    --   It looks like your installation is missing some executable files or they ended up in some unexpected places.

New build straight from CD so no issues here anymore as far as I could see in the logs.

1. 2 FXO FXSLS (In use) (SWEC: MG2) RED  It looks your PSTN line is in red condition
   

Still shows up as red :-(

# lsdahdi
### Span  1: WCTDM/4 "Wildcard TDM400P REV E/F Board 5" (MASTER)
  1 FXS        FXOKS       (In use) 
  2 FXO        FXSKS        RED
  3 unknown    Reserved    
  4 unknown    Reserved

Channel 1 is not "in use" though it's free as in no one is using it?
-plus when press green button on DECT handset I get dialtone.

However, plugging an old non-cordless POTs handset into the 10meter cable I have going from the PSTN line over to the Asterisk server did come up with a lot of noise on the line. I think it's because it's a 10 meter cable and it does cross over some power sockets so probably picking up 50Hz hum and additionally other signal residue from around (Electronics 1-0-1 long cable = antenna).
- Can't asterisk clean this up using digital filters, or can anything else be done for it?

I run my PBX in a 72" rack sitting in my living room and there isn't enough space to put the thing next to the PSTN socket!

It would also help to see the contents of the /etc/asterisk/dahdi-channels.conf and /etc/asterisk/chan_dahdi_additional.conf.

The following thread can have some relevance to your case.  Please run fxstest and post the results here.

I looked at this but couldn't figure out where to obtain fxstest from as it's not in the yum repos and Google doesn't come up with any answers either??
