Mazilo, I think Steven meant that no transcoding was required at the FS level, which was the point of Abid's question. And the main disadvantage of using bypass media is probably the NAT handling, and the lack of topology hiding.

If G729 is at both ends, then no encoding/decoding is required as the raw data can be sent straight through. This is passthrough mode. Because there is no encoding/decoding stage, there is no licence required in this case.
A more appropriate way to say this is no transcoding. Encoding/ decoding processes are still done at each endpoints on the device, i.e IP Phone, ATA, and/or computer (with softphone), and a G729 license is still required when the call uses the G729 CoDec (which is mostly paid when one acquired the device with a built-in G729 CoDec). So, to say no encoding/deconding involved and no license required are really misleading and definitely incorrect.
BTW, one can also configure his/her FS system with bypass media option to ensure the FS only does the SIP with no media handling. The advantage using this approach is to leave FS alone and free up some of its networking resounrces to handle the media during a call. There is also some disadvantages, i.e. no MOH, etc.
