Nope, the Neg (for Negotiated) Codecs indicate that you have no codecs for
a call. If you don't specify codecs, the default is (alaw|ulaw) for lines,
and the same for devices. Because you haven't changed the line stuff, it is
still (alaw|ulaw) while your device stuff is (g729).

When the device registers, it sends a message of codecs which is likely
(ulaw|alaw|g723|g729), this is check against the devices settings (g729)
which results in (g729).

It is then checked against the lines codecs (ulaw|alaw) which results in
(nothing).

Add the line allow=all to you lines section, or allow=g729. Either way,
you will only be able to use g729.

Codec negotiation:
(ulaw|alaw) & (ulaw) => (ulaw)
(ulaw|alaw) & (g729) => (nothing)
(all) & (g729) => (g729)
(g729) & (g729) => (g729)
