Hi All-Depends on the phone.. If you are using a Grand Stream then the best you will get is G.711 (+- 85Kb/s including overheads)..
I'm working on a project that will have remote (internet)access to an * server through SIP phones, either soft or hard ones.
Does anyone have any experience to share about which SIP product they are using under similar conditions, as well as which codec is being used and bandwidth usage?
TIA!

If you are using Snom's or X-Lite/X-Pro you have the option to use the GSM (+- 34Kb/s including overheads) codec..
X-Lite/X-Pro also support iLBC (+- 28Kb/s including overheads) although it does not currently work with Asterisk, and GrandStream have said they are going to support it as well soon..
All the phones have support for G.729 (+- 22Kb/s) either as standard or by buying a sepertate licence.. Including Asterisk..
Hope that helps..
