G729 30ms?

Hi,
Does Asterisk 1.4 support G729 with 30ms sample periods/packetization. I need to clarify this before buying g729 codec from digium because my provider only supports g729 with 30ms packetization intervals.

Thanks in advance.

I believe in the list of allowed codecs, you can do:

allow=g729:30ms

or it might be

allow=g729:30

can’t recall.
