g.711 vs g.729a

[burris]

In your VOIPo PAP2, where do you see that they use 729..?

I see 711 as the preferred codec on mine and at the moment, mine is and has been provisioned.

• Tim has always said their standard is G.711
• A low bandwidth option would be a great feature.
• If made available, the codec could be added to the Device display page.

Many HSI services are fast enough for G.711 and will sound better if experiencing packet loss, due to smaller portions of voice in each packet sample. If a few packets get lost they are less noticeable. Also, if a customer is determined enough to try conventional FAX, G.711 will be more successful if successful at all.

Back in 2003 when I first used Vonage, many people needed a small bandwidth codec. A soft phone today, might benefit from using G.726 due to variable access providers they could tie into.

Vonage in 2003 used:

• G.723 Low Bandwidth
• G.726 Medium Bandwidth
• G.711 High Bandwidth and FAX mode.

TRIVIA: The Cisco ATA 286 could only handle one high compression conversation at a time due to the processing power of the ATA even though the device could provide two separate lines.

On the main "Info" screen of the web interface, there is:
Call 1 Encoder:
Call 1 Decoder:

Both said G729a when she called me this morning.

Where do you see "preferred codec"?

Depends whether you have admin access to your ATA. If you got the ATA from VOIPo, I don't think you will have access.

If you do, go to the line tabs and scroll down.

Thinking some, maybe what you are seeing is the codec that the caller's service is using, since that info may be only for inbound..

Don't think so, because with my previous provider, calls to the same work phone would show G711a.

I don't have admin access to my adapter (VOIPo provided). I'll file a support ticket to see what's up and if I can be changed to G711.

Thanks,
