asterisk users - May 2004 - CallerID information on H.323 channel

I want to send date information that comes in PSTN-Caller*ID  from 
Asterisk to  a  H.323->PSTN gateway (an AudioCodes one) on the other 
side, but  Caller *ID in the phone shows

00/00/00 12:00 a.m.
"" <36>.

That is No ANI, no date.

I've found a solution to ANI problem (perhaps patch h323 channel)  but 
date still beeing a problem. Any ideas?.

Thanks
Bruno
