I also asked about the codec for SunRocket, and the rep was unable to confirm this, but he said others also asked, and he thinks they use G.711.

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.

Update for BroadVoice:

The currently have g.711u available on all proxy servers.

In addition g.726-32 and g.729a are available on the Chicago proxy. The intent is that both will become available on all proxies after testing is completed.

Please note: As of right now, no matter what codec you select for calls this will only change outgoing calls. When you get a call their servers are always going to lock on g.711u. In fact, when I made g.726-32 available as my only codec, inbound calls failed.

Sipphone is currently using G711 and GSM on their PSTN gateway; 800 numbers gateway is using G711 only, afaik

nufone.net is using G711 and G729 - will take your preferred codec

Re: Who uses what Codec?

Clarification from different CS rep:

Dialpad uses g729a for line 1. Line 2 uses g723.1.

Lingo firmware upgrade addes g726 codec to customers using the utstarcom adapter. Lingo uses g729 by default, also capable of negotiating g711 if remote end does not have g729. It's not clear if T38 has been implemented for faxing.

edit: to clarify T38 status

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?

I have no idea which codec I use. I have Vonage, and I logged into the vonage.com site and set my bandwidth to the middle. (50kbps? I think). When I have it to 90kbps, the person on the other end can not hear me clear, and they are way too loud in my ear, even with my phone volume set to low. I have roadrunner 5meg down, 384kb up.

In another subject, my VOIP quality dramatically improved as soon as I ditched my linksys router and went to a astaro secure linux firewall setup.

Through searches through Stanaphone's forums it is stated Stanaphone uses g.711u & GSM.

Just got a D-Link DVG-1402S VoIP Router activated on Lingo.
After searching down Primus's UserName/Password, I can now see that router is set up for primary = G.729a and secondary = G.711 u-Law.

Here's a nice comparison of different service providers. Codecs used by the providers are actually listed.

Great link, Phoneboy. Thanks. Not 100% accurate, but pretty close for Lingo.

Use the drop-down list, and then select the providers, and hit "compare."
