Broadvox Direct: G.711/G.729 + T.38
Packet8: G.729 (G.711 Fax)

VoicePulse: G.711/G.726-32/G.726-16
Lingo: G729 + T.38

| Thanks, nsumner. That actually clears up most of the companies I was unsure about. I thanks to the mods for sticking this. I was a bit disheartened when I saw it fall to the third page after half a day.  |

That would be G711u and G729a for QuantumVoice. You can choose and use either in the SPA-2000 config for their service.

There is a lot of information out there about codecs. This thread also mentions more links: »[Primus] What determins GOOD voice quality?

iConnecthere:
After much experimenting with iConnectHere and Asterisk, I have found out the following:
g711 - US calls, good quality.
g729a/gsm - international, at least to Ukraine. Quality is pretty horrid there. Looking for the VOIP provider that will allow g711 internationally. |

Just an FYI -
Vodavi in theirVoIP offerings use
G.711 @ 110kbps for "full" B/W connections and
G.723.1 @ 22kbps when B/W needs to be limited.
G.723.1 can sound almost toll quality when you have some control over QOS.
Do you understand the deference between
G.711u-law and G.711a-law? |

Re: Who uses what Codec?
Is that Kilobytes per second or kilobits per second? My cable connection can only do about 512kilobit upload. |

Verizon VoiceWing has standardized on G.711. G.711a as default and G.711u when the connection allows. |
