G723.1 on H.323 modules

Asterisk Asterisk Support

Dear Lady and Gentleman

Do you have any idea how to enable G723.1 on the H.323 module?
Otherwise, doesn’t the Asterisk H.323 module support G723.1 codec?

Best Regards,
Mizuki :slight_smile:

have you installed a G723 codec in Asterisk ? at the CLI enter CLI> show translation to see what codecs you can access now.

Thank you very for your reply.

When I entered “show translation”, it was displayed like below;

have you tried using g723 with h323 ? what happened ?

i’ve just looked at the h323.conf.sample and jeremy either doesn’t like g723, or it doesn’t work. perhaps you should email him (email address is in README) or preferably contact him on the #asterisk channel on IRC.

Asterisk 1.4 and newer have support for G.723 option. Try this one.
