Hello, I saw some conversation about this in the archives, but nothing definitive. If a call comes in over a CO line via the TDM400P, the Comedian Mail recording volume is so low it's inaudible. Calls coming in via SIP or IAX do not have this problem. Does anyone have any information on this issue?

This is good for about +10 dB compared to the compressed formats, for some bizarre reason. It's not just voicemail, recordings made with Record() are affected, too. There was a bug filed about this. It was marked as a wontfix, as I recall, because no one would step forward with code or $$$.

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.
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. -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Rich Adamson Sent: Monday, June 27, 2005 11:25 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] TDM card and voicemail volume> I saw some conversation about this in the archives, but nothing > definitive. > > If a call comes in over a CO line via the TDM400P, the Comedian Mail > recording volume is so low it's inaudible.

It may cause echo or excessive volume levels if you're also doing regular calls, though.
> -----Original Message----- > From: Steve Prior [mailto:sprior@geekster.com]> Here is the text of the last 2 bug comments by MikeJ (who I > would assume > closed the bug).<text snipped> I think there are three issues here: 1. The bug was originally filed as a "feature request" for a feature that would have been a work-around, at best. The actual source of the problem wasn't narrowed down until later. It probably should have been filed as a bug report, instead. Unfortunately, I fear that trying to file one now will probably just result in it being marked as a duplicate of the closed feature request. 2. I believe there are quite possibly two seperate bugs conflated in that one item. There's the recording format problem (compressed formats are at -6 or -10 dB compared to uncompressed) and possibly also a TDM-specific recording volume problem. 3. The people who are affected are not the people who are capable of fixing it, and the people who are capable of fixing it are apparently not affected enough by it to care.
