I was able to raise the volume from inaudible to acceptable by increasing the RxGain in zapata.conf by 5db. I'd rather not go the uncomressed wav route, as it will chew up storage in my email system.

It seems the greater the distance from the Central Office, the greater the problem (due to the cable loss to the Central Office plus the problem with the TDM card). Part of the problem is there are very few people that understand zaptel, wctdm, drivers, hardware (chipsets) and transmission engineering. Actually, there is only one person and he is now very busy doing other things that are apparently more important. As someone else mentioned, changing to wav format improves the levels a little bit, but its certainly not a fix. There are no known work arounds. _______________________________________________ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users The contents of this email message and any attachments are confidential and are intended solely for addressee.
