Re: [Ekiga-list] "No common Codec"

["Darren Albers" <dalbers gmail com>]

A follow-up to my own email from:
http://www.callcentric.com/faq.php?s_go=1&search=codec&go=Search#100
"For calls to the PSTN (traditional landline and mobile phones) the
following codec's can be used:

G.723 6.3Kbps
G.729A
G.711 mu-law
G.711 A-law"

So I guess I am out of luck unless I can get my provider to support
other codecs or will Ekiga support these codecs in the future?  I
understand that G729 is patent encumbered but what about G723 and
G711?
