When a remote office location is set up with limited bandwidth resources, which codec would allow the most voice calls with the limited bandwidth?
The correct answer is D. G.729. Cisco recommends using G.729a as the low-bandwidth codec because it is supported on all Cisco Unified IP Phone models as well as most other Cisco Unified Communications devices, therefore it can eliminate the need for transcoding.
