Verizon Completes World’s First VoLTE Call Using an LG Revolution

Verizon just completed the world’s first Voice Over LTE (VoLTE) call, a 33 second long conversation between their director and manager of technology using an LG Revolution.  Word got out yesterday that they would be demoing this new VoLTE service at MWC, but the brilliant idea of testing it out before getting on stage must have crossed someone’s mind.

The press release states that the service will be optimized during 2011 and available some time in 2012, although earlier reports said the Revo would have it working by launch this summer.  Either way, the service will allow for amazing call quality and super fast simultaneous voice and data.  Nice work Verizon.

Presser after the break.   


BASKING RIDGE, N.J. – Verizon Chief Technology Officer Tony Melone has confirmed that the company’s technologists placed a live, IMS-based VoLTE (Voice over LTE) call over its commercial network on Wednesday morning.  This takes VoLTE calling from a lab environment to a commercial network for the first time anywhere on the globe.

The initial call was placed at 9:54 a.m. ET Tuesday, Feb. 8, 2011 by Balaji Raghavachari, manager of technology for Verizon Wireless, using a LG Revolution 4G smartphone.  The call originated at Verizon headquarters in Basking Ridge, N.J. and was received by Sanyogita Shamsunder, director of technology for Verizon Wireless, who was also on a LG Revolution 4G smartphone in Basking Ridge.  The initial call was 33 seconds in duration.  During additional calls made that morning, the technologists were able to browse the Web and use other data services while participating in voice calls.

Melone said, “Today is another proof point that the LTE ecosystem is alive, healthy and thriving.  VoLTE will quickly become the global standard for delivering voice over LTE networks.”

“The GSMA launched a voice over LTE initiative a year ago with the aim of driving a single, industry-wide solution for voice and messaging services via IP,” said Alex Sinclair, chief technology officer at the GSMA.  “We commend Verizon Wireless for helping to make this a reality by conducting the world’s first voice call over a commercial LTE network. The progress made by the GSMA, its members, and in particular Verizon Wireless, to enable this functionality will play a crucial role in driving strong momentum and vast economies of scale for LTE all over the world.”

Subsequent test calls lasted more than 10 minutes.  Technologists browsed the Web, participated in chats and downloaded applications from the Android Market™ while on a voice call.  The LG Revolution smartphones were running on the Android 2.2 platform.

Verizon Wireless plans to enhance VoLTE with rich communications services and optimize performance on its commercial 4G LTE network during 2011.  Commercial services are expected to be available in 2012.

Verizon will showcase IMS-based VoLTE calls over a demonstration network in its booth (Hall 8, stall 8C55) at GSMA Mobile World Congress in Barcelona, Spain, next week.  For more information about LTE, visit www.verizonwireless.com/LTE.

    My question is how’s this going to work in fringe 4G areas??? Obviously, when the 4G LTE service cuts out, the phone is going to need to rely on 3G/1X service – Is your call going to drop, or will it continue the VoIP call using the lesser data service? How well will the 3G or 1X service handle a VoIP call, if that’s the case? – What kind of quality degradation would we see?
    I don’t see how you could go from a VoLTE (VoIP) call to a traditional cellular call seamlessly. A couple years down the road, once LTE is fairly ubiquitous, this could be a great thing; but until then, I don’t see this working out that well except for metro areas with good 4G coverage.

    I want this phone, but if it really is a single-core Snapdragon, and not a dual-core Tegra 2, theres no way im jumping on it. Plus, i just dont really like LG.

      I like LG TVs and home theaters. I like my U740 simplephone, I’d be willing to give them a shot with smartphones. Keep an eye on how they update this one. As of now I’ve limited my next phone to HTC, it would be nice to have LG as an option too.

    i think i want this phone over the bionic. even tho every lg phone i had of theirs was defected.. i still think they have what it takes!

  • Mr.Joe

    OH great. Just another requirement on my phone list. First SVDO capabilities but now I want VoLTE.

  • How does this sound. Put a good headset on the phone. That will make it sound 100X better. Droid Incredible headset sucks,

    Will 4G LTE phones that are coming out this year will be able to switch over to VoLTE?

  • shr1k3r

  • its nice to see LG taking android seriously.

    Given that they used a Revo and not the T/bolt, can we assume that the T/bolt can’t (at least currently) do VoLTE? No big deal of course as VoLTE won’t be rolled out until next year, but an interesting question imho…

  • Skychet

    correct me if i’m wrong (and i probably am, just confused about this), but isn’t LTE verzion’s fancy wording for 4G? and sprint’s had a 4G phone and network since the summer? clarification? i’m dumb

    • SoCalVoIPFan

      No – LTE is a technology. 4G is just a (massively overhyped) marketing term.

    • Mr.Joe

      4G stands for 4th Generation. Think of 4G like an umbrella term. A bunch of stuff falls under 4G. Just like how EVDO and HSPA falls under 3G. WiMax and LTE are considered 4G technologies.

    take that sprint

  • pope wilson the third

    maybe a noob question, but will this be limited to 4G phones, or will our 3G’s have this ability too?

    • palomosan

      If I’m not mistaken, it’s only available for 4G phones since that’s one of the selling points of LTE.

      By the way, that phone looks good.

    • Mr.Joe

      No. VoLTE means Voice over LTE. Since LTE is 4G I don’t know how a 3G phone would be able to do it. Look up SvDO.

    Very cool!! So, if they now have figured out how to do voice and data simultaneously on 3G, will they be able to do that on 4G too?

    • exactly! in fact it was revealed a while ago that the Thunderbolt will be able to do that, and that Verizon reps at the stores arent supposed to talk about it oddly enough

        What’s the thunderbolt? That does not exist
