    Call Quality

    Let me preface this post by stating that I realize call quality is a subject topic. With that out of the way I wanted to ask about the perceived call quality other users have with the following conditions:

    1. Coming from iPhone 7 Plus on Verizon and T-Mobile
    2. Coming from T-Mobile and Verizon to AT&T
    3. Call Quality as it relates to VoLTE on all carriers


    I recently switched from Verizon to T-Mobile to AT&T. My Call Quality rankings would be T-Mobile to Verizon to AT&T in order of best to worse. All these calls are made on VoLTE. Now that I am using a Galaxy Note 8 on AT&T in Phoenix, it seems my Call Quality has been reduced since I started service with them 2 months ago.

    People I call tell me more frequently (than when on T-Mobile and Verizon) that they cannot hear me clearly and sound broken up, and my perceived quality of them on the other end is also not that great. There is a noticeable difference in quality since coming from T-Mobile and Verizon on the iPhone 7 Plus where calls on VoLTE were about as good as I have ever heard (on par with VoIP calls from Skype, etc.).

    Since I have switched to AT&T I have traveled across the country and have always had a good LTE signal with great speeds. However, call quality has left a lot to be desired. I have also noticed when I do call my father who is also on AT&T the call is crystal clear, but this is not always consistently clear, meaning it varies from call-to-call.

    In conclusion, I am hesitant to leave because the consistent speeds, LTE availability (even deep in Muir Woods National Forest for those of you who know where that is), and promotion with DirecTV. What are you experiencing and can you add anything to the discussion?

    Regards,

    Ah the old call quality conundrum. Lol. Well I'll start by giving you my experience. Call quality on Verizon with a iPhone 6s plus was pretty good. Then we moved to Sprint. Call quality there was almost as good on 3G was almost at good a Verizons VoLTE, this was with both a iPhone 6s plus and a note 5. So we come over to ATT a year ago and call quality isn't as good as on Verizon but comparable to Sprint. Now I have moved from a iPhone 7 plus on ATT to a note 8 and unexpectedly got better call quality.

    I don't have any experience with TMobile sadly. But I will say that I have had a few SUPER clear calls with ATT to Verizon users. I don't think I've made to many calls to ATT users except for the wife and when I call her it's pretty good unless she is in the car or on her apple watch. I can't understand why anyone would want to patch a call in through a cars Bluetooth. That sounds like total crap. Same for the apple watch.

    Call Quality

    iPhone 7 Plus here, tested on all carriers except sprint (used a nexus 6p for that)

    Call quality ATT/VZW with T-Mobile being the worse with the iPhone.. there is also some sort of static noise on T-Mobile calls across 5 different model iPhones I’ve noticed as well. I did use an Android with T-Mobile once and it seemed OK.

    Most of the people I know are on ATT and as long as they are on LTE and using a phone that supports hdvoice every call is crystal clear.

    Whenever I test out Verizon, the calls between them and att it’s hit or miss whether you will have an hd voice call or not.

    Thank you for the quick responses... I know this is a heavily subjective topic. However, I wonder if what I may be experiencing is a hand-off to 4G for voice on AT&T. What are your thoughts on that? Does AT&T do this? If so, then how would I know? I presume that my calls are VoLTE because I am in a strong LTE area.

    Do you have Noise Suppression & Voice Clarity selected?
    As a US citizen I have the right to criticize my government. My thanks for this is endless in magnitude.

    Don't have a Note 8 but found this on a Note Edge maybe this'll work.

    Yep, the same reason I dumped Verizon. I tried VoLTE on various phones & it was too unreliable. Never realized how awful 1x sounded till I switched to AT&T. No need for VoLTE anymore as UMTS comes close to landline call fidelity.

    I do wish VoLTE worked better for me, but gave up after many attempts. Hoping it will get better in the future. . . . . .

    I can say that on Sprint I recently tried the service and call quality for me was really bad, AT&T is good since 4G seems to be clear calling at night but T-Mobile seems to be the best in my area.

    I'd suggest turning off VolTE.

    As other's have said, 4G sounds pretty good (better than 1X) and it's generally more reliable now anyways. VoLTE can sound really good, but I know in weaker signal environments it tends to break up badly. It sounds like 1X at -120db or something. I am not sure why at&t's network doesn't see the packet loss and switch to 4G as well as it used to. I had to turn it off my mother's line as parts of her house seem to have slow uploads on LTE, while 4G is solid throughout.

    Let's keep in mind that HD Voice (not necessarily VoLTE on it's own) across AT&T, Verizon, and T-Mobile should theoretically be the same; it's the same codec, AMR-WB 12.65kbps. The only thing that would vary would be how the network transmits that data, as QoS, network equipment, backhaul, etc. all come in to play.

    That being said, with all of the markets I've been in (SWVA/NETN, Raleigh NC, Atlanta GA, many parts of FL), unless there was an issue with signal quality/levels (read, at the edge of a cell or in fringe coverage environments), I've not experienced poor audio quality. When calling someone that is on an interconnected carrier (example, Verizon and AT&T are interconnected now), and VoLTE is enabled on both ends, it sounds just as good as calling someone on the same carrier as me (AT&T). Absolutely no difference in quality.

    However, when speaking to someone who ultimately doesn't have an end-to-end SIP connection with me (read, VoLTE isn't interconnected), audio quality is landline quality, as the codec switches back to AMR-NB (usually 12.2kbps for me) and transcoding occurs.

    I've spoken to people on Sprint from my AT&T line, and transcoding sounds just about as bad as Verizon's 1x voice quality, which is terrible but passable.

    In short, though, find what works for you. If AT&T's voice network really bugs you, switch to another carrier if it's a big enough deal.

    Also, disabling VoLTE will only help if the LTE network in your area is experiencing problems, which I'd suggest submitting a MTS for anyway. Disabling VoLTE will most likely make you hate AT&T's voice network more, as you wouldn't be experiencing HD voice with those you potentially enjoy it with now.
