- martyvis 4y agoWhat? HD Voice using VoLTE or WiFi Calling is miles better than any land line phone
- solardev 4y agoI'd take a landline over the inconsistency of cell calls any day. Maybe peak/maximum quality is better with today's tech, but reliability definitely isn't. I would bet average quality of calls has dropped too. HD voice is a carrier specific thing, no? Most of the time I can barely even hear the other person, much less have HD anything.
- babypuncher 4y agoI think you have been misinformed. Voice calls over plain old telephone service were band-limited to <4khz decades before cell phones became popular. This was necessary in order to cram more active calls into our existing telephone infrastructure. Digital phone calls today are way better.
- toast0 4y agoToday's g.722 (HD Voice) is better, but GSM codecs are also 8kHz sampled, then lossily encoded. If the compression is appropriate, gsm is 13-bit per sample vs 8-bit per sample commonly used for POTS (minus robbed bit signalling in the US), but if the compression isn't appropriate, you get some pretty nasty artifacts. Encode/decode delay can be significant in some applications, but since GSM is TDMA anyway, you're going to have buffering and may as well use that to encode; a T1 PRI multiplexes one sample at a time, so a lot less delay there.
- ghaff 4y agoI’m sure that’s all true. I’m also pretty sure I wasn’t regularly shouting into my AT&T landline “I can’t hear you!” Obviously we’ve gained a lot with cell phones and portable music playing but it’s been mostly at the cost of consistent quality.
