So most of you know that the quality of cell phone calls ranges from almost acceptable to dreadful. More often than not, it’s the latter, as a\u00a0voice at the other end of the call is often immersed in\u00a0a digital haze that makes it a little hard to understand. To think that all of the advancements made in technology still fail to match the voice quality of the analog telephone system in the late 19th century.<\/p>\n
Some of it is no doubt the result of the move\u00a0to digital cellular systems over the years and the efforts to pack as many connections as possible in a single tower to handle as many paid customers as possible. So voice quality is less important. These days it’s all about data anyway. People talk via messaging or email, so having a high quality voice connection may not be so important.<\/p>\n
In saying that, my experiences with cell phone systems over the years led me to AT&T, then known as Cingular. I signed up with the service primarily to be ready for the iPhone just as soon as my contract with Verizon Wireless had ended. At the time, in 2007, I was very disappointed with voice quality on the Verizon system, and I came to prefer AT&T, since the best connections seemed more analog, more akin to a traditional landline phone connection. But network reliability wasn’t as good. I encountered more dropped calls.<\/p>\n
In passing, the dropped calls are largely history, at least in the areas to which I travel.<\/p>\n
That takes us to HD Voice, which is a technology designed to provide higher quality audio\u00a0on a cellular connection. Referred to VoLTE, which is Voice over LTE), it’s similar to a VoIP connection on a traditional Internet network. When two parties with HD-voice mobile phones are connected in a network that supports the feature, call quality is noticeably better, which is mostly my perception from personal experience.<\/p>\n
The wireless carriers have had different rollouts of HD Voice. To AT&T, it’s clearly been a work in progress.<\/p>\n
So that takes us to a problem I occasionally confronted when calling someone on my iPhone. The ringing sound seemed much slower, deeper. When someone answered, they’d be speaking real slow too, akin to playing a 78\u00a0RPM record at 33-and-a-third RPM. But that assumes you’re familiar with vinyl, or just imagine playing any recording at a slower speed and you’ll see what I mean.<\/p>\n
With AT&T, I only encountered that problem when placing a call, not receiving a call. Usually, when I hung up and called back, the problem was gone.<\/p>\n
I’ve mentioned my encounters with AT&T support before, but it has taken four calls, the latter with a higher level of technical support, to get the extent of the problem and it’s expected solution.<\/p>\n
So during the first two calls, the technician claimed to be making changes to the provisioning of my iPhone. Since the phone numbers were ported from Verizon, that condition supposedly created potential integration issues. Or perhaps the technician was shooting from the hip, since the cause appears to have\u00a0nothing to do with the source of my phone\u00a0number.<\/p>\n
Each time, I concluded the call after being told to power down my iPhone, and power up again. This would allegedly activate network changes that would address the problem. But I have come to feel that they were just mollifying me or hoping that the act of power cycling would clear up the connection glitch.<\/p>\n
It didn’t.<\/p>\n
But on the second call, the technician promised to send the problem up to engineering, and I should call back if it recurred, which it did a few days\u00a0later. You see, I don’t make phone calls all that often.<\/p>\n
On the third call, the technician claimed that engineering wasn’t able to duplicate the problem, and suggested I call the number I received in a text message a few days prior.<\/p>\n
That’s when I finally had what seemed to be a more logical response.<\/p>\n
The higher-tier technician seemed totally aware of the problem, which, he said, involved glitches using HD Voice, a sort of digital mismatch he tried\u00a0to explain. He claimed it was a known issue\u00a0and that it\u00a0should be resolved by the end of the year, that I should call back if it wasn’t corrected. In the meantime, I was advised to turn off HD Voice on my iPhone to remove\u00a0the symptoms.<\/p>\n
That’s done by going to Settings > Cellular > Cellular Data Options > Enable LTE > and switching from the Voice & Data option to Data Only. It seems more complicated than it is, but making that one change takes only a few seconds. Obviously such changes on an Android phone will involve far different settings that may depend on the device\u00a0and OS you’re using.<\/p>\n
What I did notice was that voice quality seemed to degrade slightly without HD Voice, but the problem didn’t repeat itself. At least not so far. If the technician’s answer is accurate, that\u00a0makes sense. The new service is still being refined on the AT&T network. If you’re a customer, it may not even be active\u00a0in your city, in which case the HD Voice option will not be available.<\/p>\n
Now the technician claimed that support people had ready access to technical information about known problems and solutions. It surprises me \u2014 but not a lot \u2014 that the first tier AT&T techs were totally ignorant of that information, which means they weren’t paying attention, or made no move to consult such data. Perhaps they\u00a0were more interested in getting me off the phone and moving on to the next customer.<\/p>\n
I’ve said previously that AT&T’s customer service has nosedived since\u00a0the acquisition of DirecTV. It may not take a further hit if the bid to merge with Time Warner is approved. That’s only because Time Warner doesn’t provide direct services to customers that require tech support. Or maybe AT&T will see the need to cut costs even further.<\/p>\n
I’ll let you know if the HD Voice problem \u2014 if that’s what it is \u2014 has been resolved.<\/p>\n","protected":false},"excerpt":{"rendered":"
