Is VoIP Google's Next Frontier?

Posted by CmdrTaco on from the rumor-mill-keeps-running-on-overdrive dept.

WindBourne writes "Apparently, Google is looking to some degree at VoIP. Of course, the question is whether they will support such items as Asterisk and FreeWorld or will they simply buy another company and tinker from that end."

  1. Quality? by Sierpinski · · Score: 4, Interesting

    A friend of mine has a VoIP service, and I think its horrible. He cuts in and out all the time, low volume (even though he says he's almost shouting) and there's constant static. I don't know who his carrier is, but if thats any indication of the general quality of VoIP, then I'll stick with my landline and cell phone.

    Anyone else have good or bad experience with VoIP quality?

      If you've ever called anyone using a LD calling card, or if someone has called you with one, you've probably used VoIP and not even realized it. Most LD calling cards use VoIP carriers to cut costs.

      My parents call us all the time, and it sounds just fine.

      (Also, I my work desk phone is IP, and it sounds great. Of course, I'm a network engineer for a IXC/CLEC/ISP/VoIP provider. So I may be biased about our service :) .)

      It is all in the codec (and configuration thereof) that your provider uses.

      Are you for real ?

      The codec determines the bandwith/voice quality tradeoff that's true but thats less than half the issue. The real deal is quality-of-service (QoS) in layer 2 (ethernet/atm etc) and layer 3 (IP). When you have QoS in hand and a reasonable bandwith ALL-THE-WAY through then you've got a real VoIP system.

      I happen to do this stuff for a living and QoS is rather hard. In particular when you don't have much control over your customers (crappy) networks.

      The real deal is quality-of-service (QoS) in layer 2 (ethernet/atm etc) and layer 3 (IP). When you have QoS in hand and a reasonable bandwith ALL-THE-WAY through then you've got a real VoIP system.

      Both the codec and the connection are important. The codec and the bit rate determine define the upper limit on the audio quality. If the codec can't reproduce the audio accurately at the specified bit rate, your call is going to sound lousy even if every packet arrives instantaneously.

      On the other hand, if your connection is lousy, either can't deliver the bandwidth required, has high (or highly variable) latency or frequently drops packets, you're going to have other problems.

      I use Vonage on a Comcast cable modem, and the quality is generally excellent, unless I'm overloading my cable connection. I use a Linux router configured to do traffic shaping/policing and to give precedence to the VOIP traffic and that *mostly* works, but people I speak with report the occasional garble or dropout when I'm transferring large files.

      My boss uses Vonage on a fairly low-bandwidth DSL connection and doesn't have a smart router to prioritize VOIP traffic, although he does put the Motorola VOIP box in front of his Linksys router/WAP, so the Motorola box should be able to do prioritization. In his case, his VOIP service gets really bad when he's sending large e-mails.

      Assuming the connection is good, my experience with Vonage is that Vonage-to-land-line calls are excellent and Vonage-to-Vonage calls are astoundingly good. I don't know if I'd say "CD quality", but the audio is far clearer and louder than any phone connection I've used.

      I do notice some latency, but I think that's only because I'm paying attention. After scrutinizing my VOIP connections for months, I now notice *massive* latency on my cellphone communications. My cell phone has almost twice the latency of my VOIP phone, but I never noticed it before I got VOIP and started obsessing over it.

      BTW, it's fun to call my cell phone from my VOIP phone and hold them next to each other and listen to the "feedback". The large total latency (Almost 250ms, I'd guess) leads to some really interesting "echoey" feedback effects.

      Actually, I think they both were discussing the merits and realities of end-to-end QoS for VoIP. The difference in perspectives is that the great-grandparent is discussing consumer VoIP services running over consumer broadband, where end-to-end QoS is a remote possibility at best, while the grandparent is discussing a QoS-enabled and geographically diverse enterprise network running VoIP.

      Either way, IP QoS is not usually defined in the various terms you used. IP QoS commonly refers packet delivery delay times, jitter (i.e. differences in delivery delay for packets in a single flow), L3 packet-marking (IP Precedence, Diffserv), L2 and MPLS packet/frame-marking (802.1Pq Ethernet CoS, MPLS EXP), and egress-queuing (priority queues, class-based weighted fair queues, etc.)

      While call-control servers, IP phones, PSTN gateways, etc. can mark packets with IPP or Diffserv, it's the routers and switches (e.g. the network) that prioritize packets by queuing and processing them based on their markings.

      They also provide for mapping IP-layer packet-marking into 802.1Pq and MPLS marking when the originating equipment doesn't support those protocols. Finally, routers and switches may use traffic identification methods (source IP, destination IP, source port, destination port etc.) to mark or re-mark certain packets, if required.

    It makes perfect sense to me. Everyone keeps saying that VoIP will be the end of the traditional phone system. So, what's everyone waiting on? Probably, a big company like Google get behind it and ensure that it's reliable, easy to use, and accessible.

    What's more, imagine how valuable a Google ad would be if that ad resulted not only in a visit to your website but also a call to your business. Advertising has always been about getting calls; this makes it that much easier.

  8. we are google, you will be assimilated... by kloidster · · Score: 2, Interesting

    Google is to the information-age as Microsoft is to the computer-age.

    As the web grows, their (or anybody else's) index will take longer to update, introducing a lag as to the relevancy of their links. They must know this as they are apparantly moving into new areas to grow their revenue. I wonder if they will be as profitable in things other than pay-per-click advertising...this move into VOIP seems like a move out of desperation.

    [As far as those who contend the Microsoft analogy, then I would have to argue that google-bombing is perhaps the equivalent to an information virus. Sure it doesn't crash your system like a normal virus on an OS does, but it does crash the relevancy of their index.]

    voip is still very landline-like experience. and the truth is that very few people(that are under 40) get landlines anymore here in finland when they move to a new apartment. pretty simple reasons too.. landline per minute prices are not attractive when calling to cellphones and 99% of your personal calls would be to cellphones(if i get a call from my grandpa.. it's from a cell. if i call my aunt it's to her cell, if i call any of my friends it HAS to be to cell because they simple as that don't have landlines - and if they're home and i'm home i could just as well skype).
