G711 is the only available codec on SIP trunk until CM 7.0 due this fall. You should be able to use transcoders on the IPIP GW if you need to send the call as G729 to the privider.

One the 2821 you will need to run the CUBE feature, aka ip-to-ip GW, go over the admin guide and I think most cases are covered in there.

Hope this helps, please rate post if it does!
