This has nothing to do with the card. Format 256 is G729, it looks to
me you're SIP phone is trying to place a call to the PSTN using G729,
since the PSTN only supports alaw/ulaw (depending on the type of
channel), you need to transcode the call, and you don't have G729
codec (you need to pay for it).

Sangoma offers D100 card which can do the transcoding to G729 in
Asterisk. But the easiest solution is to switch the codec in your
softphone to ulaw/alaw or something that is supported natively by
Asterisk without extra licensing required.
