asterisk users - Jun 2005 - Segmentation Fautl / Core Dump with G.729

Hello, 

Has anyone experienced a segmentation fault in asterisk for using G729
against an AS5300 in SIP ? 
I'm having this problem. Also, any other codec I use gives me incompatible
media (can be read in SIP DEBUG messages). 
AS5300 configured for multiple codecs, so is Asterisk. 
Tried G711u/A G723 and G.729. Any clues ?

Regards,

Jorge A.

Info: 

Asterisk ver 1.0.7 stable
Using AMPortal 1.0.0.8
