[asterisk-biz] G.722 VoIP Providers

[Mike 'DarkFlib' Preston]

Not if you want wideband support, since PRIs use an 8KHz sampled channel and
trying to squeeze 16KHz down it just isn't doable. Its pretty much limited
to data networks only...

To allow wideband support to a PSTN gateway it would need to be resampled,
and its not just the small hit of transcoding, half the data needs to be
thrown away in one direction (essentially) and the data needs to be doubled
in the other. Simply doubling the samples or throwing half away isn't gonna
give you perfect results.

I hope this explains it a little.
