Rich Adamson a �crit :
would like to know if some of you have tested asterisk connected to an EADS 6550 analogique PBX (also know as Nexpan50).
Our set up is a Dell Optiplex with 1 TDM400 4 FXO, 1 TDM400 4 FXS, (no other card, each of them have their own IRQ) all ports connected to the EADS. We have GS ATA286 as EP. Calling from ATA to ATA give a perfect sound. Calling to PSTN numbers or reverse side, give echo.
We can do what we want in zconfig.h (STEVE2, MARK2, MMX, AGGRESSIV_SUPPRESSOR, NOECHOCAN_DISABLE) or zapata.conf (tx gain=-10.0, echocancel=32 ... 256,), test with differents POTS phone, it change nothing. We even didn't notice changes between our various changes in those files (and yes modules where unloaded between each test). Always the same echo.
So know we start to doubt that this echo problem is asterisk related but perhaps more to the PBX. That's why we ask if some of you have/had similar setup with this PBX and if there is a solution.
You didn't mention what country your in; if you outside the US, be sure to config the TDM-fxo card for your country (eg, line impedance).
France.
You mention echocancel=32, etc, did you try echotraining=800?
Yes. It create a second echo :-(
Do you have this setup with the standard zconfig.h (MARK2)?For my TDM-fxo in the US, using the following on each channel works fine:
echotraining=800 echocancel=yes echocancelwhenbridged=yes rxgain=5.0 txgain=0.0
I might have missed some of your earlier posts relative to this; just catching up on over 500 emails from this list.
I've not had to configure a TDM for non-US support, but I know
for an absolute fact (based on 20 years of detailed telephony
engineering experience) that you have to config the TDM card for
line impedance, etc, for your country. If you've not done that,
start there. (Think that's an optional parameter when loading the drivers.)
I update asterisk from cvs-head about every two weeks or so, and always stick with default values (including zconfig.h). So, yes I'm using the default echo cancellation, etc.
There has not been very many changes associated the the zaptel
source code and the TDM-fxo drivers. Certainly not necessary to
use the latest cvs-head at all; anything from the last few months
should work.
My /etc/zaptel.conf is adapted to country:
loadzone=fr defaultzone=fr
Asterisk stable 1.0.5.
If you're telling that I have to pass parameters to module when loading, I checked with modinfo wctdm (at office I have head version) and options I have are those:
[EMAIL PROTECTED] asterisk]# /sbin/modinfo -p wctdm debug int loopcurrent int robust int _opermode int opermode string timingonly int lowpower int boostringer int fxshonormode int battdebounce int battthresh int alawoverride int
Pardon my ignorance but no one of them remaind me to impedance. And for what I saw earlier in the source file, those informations could be updated with the value of the zaptel.conf file.
Thanks for your help -- Daniel _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
