Traditional telephony over a copper wire is comparable to voice codec G 64kbps. HD Voice is a term that has come into the industry and can be seen on the packaging of most IP phones. Wideband means a wider spectrum of sounds, thus creating a fuller and higher quality sound stream. Yes, the call will proceed as normal. That said, if the two parties in the call are using different codecs, then a task called transcoding the process of converting a voice signal delivered in one codec, to a secondary codec has to happen to manage the call.
If the user and the ITSP are using one codec and the PSTN carrier or mobile carrier are using a different codec then again transcoding will happen to manage the various legs of the call. HD voice will only truly happen if all parties are on the same codecs of on variations of HD codecs. Well, yes and no.
If all parties support it, then the call quality is much clearer, but if not, then the standard common codec, which in almost all cases is lower quality than HD voice, will be used. Always ask you ITSP what codecs they will provide. The standard codecs are G, G, G and where you can try and use G as a minimum.
G is compressed so that it uses less bandwidth at the cost of some sound quality, though it is still more than good enough for most calls. There are some additional considerations as well.
G requires a license to use, so make sure it is supported by your provider. B Additionally, since G is not compressed, there is a greater chance of call quality being impeded by insufficient bandwidth on the customer side or by a packet being heard out of order. With G, the compression provides some buffering time in transit a few milliseconds, unnoticeable to you or me that helps give the codec a chance to correct out of order packets and constrained bandwidth.
If you have a lot of bandwidth and need the high quality for, as an example, transmitting music over a call, then G may be suitable for you.
