Hi guys

I recorded some nice IVR prompts on my PC, when I transfer them over to my elastix box., They sound really low in volume.:(

I searched and some posts say to increase the rxgain and txgain on zap files. I've tried and had no luck. Then again
Elastix has a bunch of modified files.
zapata-channels.conf
zapata-channels.conf.bak
zapata.conf :blink:
zapata.conf.replaced_for_elastix :blink:
zapata.conf.template
zapata_additional.conf

Which ones are the "live" ones?

all ideas pointers and suggestions are welcomed.

thanks

The rx and tx gains would only raise the volume of any digital or analog cards "such as T1 or fxs/o" you have in your pbx. Can you hear callers/ees at an optimum level? I would suggest rerecording your greetings. Perhaps record from a phone for a test to see if it truly is elastix passing on low audio.

I would try recording at 8khz and saving as a mono wav file. Then upload to freepbx.

BTW. rx and tx can be changed from
/etc/asterisk/zapata.conf

they look like this

rxgain=-4.0
txgain=-4.0

hope this helps.

Hi
I tried 8k 16bit WAV, 44k 43bit mp3s, anything I upload sounds low. If I record it from a phone, it sounds nice and loud.

my rx tx gains are default 0.0. I tried changing them, but hear no difference.

thanks

Is freepbx set to convert the file upon upload? If so, disable it.

also note, that after you change the rx tx gains you either have to amportal restart

or

asterisk -rvv

reload chan_zap.so

before the settings will take effect.
