Speex would be your best bet. Uses slightly more than what g.729 uses, but it's completely free and open source. You can use GSM too, but iirc, the patents with that codec should have been expired quite some time ago. On Thu, Oct 21, 2010 at 7:34 AM, Nyamul Hassan <mnhassan@usa.net> wrote:
But that doesn't mean that license isn't required, does it?
I was more interested in a free to use codec comparable to G729 in terms of both bandwidth and quality.

Any one know of a comparable low bandwidth codec that works for mobile based softphones?

Just curious. If a G729 CoDec is a MUST and unless you prefer to use a
SIP
compliant ATA device that already comes with a built-in G729 CoDec i've had good results with G.729 with audio quality and bandwith - especially with ADSL where uplink is the bottleneck. My hardware-sip phones (Snom, Siemens) are equiped with the g729 codec, the sip provider too.
