When enabled, the service parameter allows Cisco Unified IP Phones (such as 7971, 7970, 7941, 7961) to negotiate and use the G.722 codec when calls are within the same region.
It uses the same BW as G711 but the technology used differs on the fact G722 has a higher sampling rate which carries more info in the same BW as a G711 call, it's explained better in the link in case you want to know some more on this codec
since the codec has a better quality over the same BW as G711, if the phones are capable of using it, they will, even if you have the region to G711. if you have the region configured to a codec that uses less than 56K it won't work and then you will use the codec from the region
