Re: [Broadvox Direct] Broadvox and BroadVoice join the VoIP Fray
Well, I hope they add the option to use g.711. While g.729 saves bandwidth, the problem is you can't undo compression. Why is this bad? I'm finding that calls from either my Broadvox lines or my Vonage line are distorted when they're set at g.729 and I call a GSM cell phone, which I think recompresses the already compressed signal. |

| You are close. G.729 is uncompressed (any compression for that matter) at the gateway, prior to hitting the PSTN. Then, your call makes it to the cellular phone that compresses it again, and again taking away some of the bandwidth.
To address your statement, yes; adjusting the CODEC in which you use as well as many other features will be available on the portal.

The problem being that each time it's compressed the sound degenerates by a factor because the codecs are lossy compression.

That will be awesome. Just hope my broadband is up to it. Adelphia isn't that great around here and all my past attempts at using g.711 with this ISP have turned out rather badly.  |
