<div>
For AMR(-WB) you'd need either a 3rd-party software implementation or the Sangoma transcoding hardware. FreeSWITCH's modules can be compiled against a AMR library implementation if you can find that library and obtain the required licenses. If you're worried about load, the Sangoma hardware takes most of the workload off of the CPU onto the chipset. Either way as already noted you're going to have to obtain the AMR licenses yourself.</div>

AMR is not an HD codec. There is a wideband version of AMR, called<br>
AMR-WB, but when people just says AMR they are talking about the narrow<br>
band codec.<br>
