asterisk users - Nov 2004 - Zap - 256 format frames

Any ideas on this warning? If I call this number, sometimes I get this error
and sometimes the call goes thru fine. Why would it work sometimes?

"show codecs" in the Asterisk CLI will tell you the number of each
codec.

If you want to use G729 and the "t" or "T" option on the
Dial() line
you must purchase the Digium G729 codec.  Asterisk CANNOT do pass-thru 
when using "t" or "T" options on the Dial() line.  There is
no way
around this.

I guess I should have mentioned that I have 10 codecs:

0/0 encoders/decoders of 10 licensed channels are currently in use

Any other ideas?

Well, it seems that Zap cannot do 729 at all:

channels/chan_zap.c (line 4156):

if ((frame->subclass != AST_FORMAT_SLINEAR) &&
            (frame->subclass != AST_FORMAT_ULAW) &&
            (frame->subclass != AST_FORMAT_ALAW)) {
    ast_log(LOG_WARNING, "Cannot handle frames in %d format\n",
frame->subclass);
    return -1;
}

Seems that Zap can only do slinear, ulaw and alaw. So, how do I force my zap
card to only to alaw?

If I have an incomming Sip 729 call, shouldn't asterisk convert it to 711 to
go out the zap card? I have 10 g729 licenses.
