VoIP without Computers Jangl in the lead, 8x8 close behind The whole point of VoIP calling systems used to be that your phone call was routed through your computer in order to streamline productivity and decrease calling costs. Changes in the VoIP market lately seem to indicate that the computer part isn’t really so necessary. Not only is mobile VoIP on the rise but prominent VoIP companies are beginning to introduce “direct calling” features which bypass the computer. Along with a slew of other announcements, Jajah recently announced the launch of Jajah Direct. Using dial-around services, you can receive a local number through Jajah for every long-distance number you normally call. (A breakdown of how it works can be found here.) And Jajah isn’t the only player in the game. 8x8 also launched a no-computer-needed (but software-based) method of making international calls at a low cost. The two services differ slightly but indicate a changing VoIP market which appears interested in mobile solutions.

Carrollton, TX | Re: CDV? said by dadkins:Anymore, I don't know what to think about my CDV(Comcast Digital Voice). Some people try to tell me that it *IS* VoIP, others try and tell me that it is different than VoIP. It depends how you define VOIP. Using the correct, technical, definition of VOIP as Voice Over Internet Protocol then CDV is definitely VOIP because the data to and from your CDV modem is sent as IP packets. However, from a marketing perspective, the term VOIP tends to be used for third party products that are independent of an ISP and route the calls, at least for part of their journey, over the Internet. In this sense, CDV isn't VOIP because all the IP portion is carried on Comcast's own network. | |
| | | | said by dadkins:Anymore, I don't know what to think about my CDV(Comcast Digital Voice). Some people try to tell me that it *IS* VoIP, others try and tell me that it is different than VoIP. If it is VoIP, then it is already bypassing the computer(ARRIS eMTA). If it is NOT VoIP, then WTF is it? [/Sarcasm] Nevermind, not important.    It works. It's less expensive than a POTS line. It's crystal freakin clear. VOIP - Voice Over Internet Protocol - uses a HSI connection and can be interrupted by Net congestion.
Cable Digital Voice (Have It) - Uses Softswitch Internet Protocol technology but travels over the cable cos private Backbone not the Net, No HSI required, has full E911 they set up.
FIOS Telephone is pretty much the same as CDV since it also uses the private backbone, softswitch, and IP technology.
Regular Copper Telephone - Actually, AT&T is implementing softswitch to use IP routing of phone calls since it is cheaper and doesn't required huge Frame Relays (that big building where the "Frame" is). The "brains" of your phone service, in many places, is on a "slick" (fiber) and no physical "brains" (phone system) required since it is all computer software. AT&T (really Bellsouth areas) calls the system "Redback" since it can remove employees known as Frame Techs from the equation since it is all computer. It actually is digital phone till it reaches your NID then converts back to analog. Businesses install their own NIDs and make it digital (although most just install T1s or T3s or OC3 (or highter) lies). Eventually the COs will just be nodes (same tech as a Cable node) like cable or FIOS has.
Softswitching technology, using IP to route phone calls all by software, is about 50% cheaper than a copper plant. It is estimated to be eventually 90% cheaper. Eventually, this is the reason Verizon will have to dump its copper plants since they are no longer needed. 1 fiber line, a slick, can carry about 10 billion simultaneous phone calls at once. Softswitch only requires about 30-50 kbps for a phone connection.
Who has the most phone lines in one building?
The New York Stock Exchange. It's been fully-fibered for about 10-15 years or so. It has about 10 phones lines per square foot. Of course, if the NYSE ever uses the NASDAQ system, NYSE "seats" will be useless and worthless since no floor traders required. The NYSE has tried to implement it but those multi-millionaires on the floor like their jobs and the brokers have blocked it for about 4 years.
The NYSE uses about 100-200 gigs of bandwidth a day so I've been told. A trade can be executed in about less than 1/10 of a ms.

| Re: CDV? Your definitions are completely arbitrary and misleading.
CDV can be interrupted by congestion, as can any packetized method of data transfer.
I have a Cisco VOIP system in the office that doesn't use an internet connection. We connect to other offices via dedicated DS1 circuits and have a PRI to connect with the outside world. Still counts as VOIP.
WTF is Softswitch Internet Protocol? And where did you find that definition of Frame Relay? | |

Those 24 channels can be voice or data. Any that are channelized as voice usually go through the bell copper network to either bell's switches or a CLEC's switches to route your calls. That's strictly analog/digital voice and not VoIP.
If the T1 channels you're running your VoiP service are channelized as data, then yes, it would be VoIP.
However it sounds like you have a point to point DS1. Most likely it's all channelized as data in order for your VoIP product to work.
Just extra info to help

Like I said, we have a PRI for 23 channels of voice to AT&T's CO (1 channel for signaling). Remote sites are connected via DS1s for both normal data and VOIP packets. | |

You set up the equipment, I got you there. I'm actually talking about how the copper is set up on the end of the ISP/Carrier (AT&T) of the copper.
The T1 (24 channels) or PRI (23 channels + D channel) are channelized by the carrier. I used to work for a CLEC and saw how provisioning took individual channels within a T1 and channelized them as data or voice.
But, again, if that's not the way yours is set up.. no worries. | |

Smithtown, NY | Comcast has CDP and CDV.
CDP = Comcast Digital Phone
CDV = Comcast Digital Voice
CDV is using their NCS/SIP (Session Initiation Protocol/Network Call Signaling) offerings as most other providers refer to VoIP.
The CDP offering is actually something along the lines of GR-303, it's still used by Comcast in some parts of their footprint probably because they don't have the demand/chance of recovering their investment to conver to CDV.

So, whats the big deal? I think the article is referring to companies developing systems that use VOIP to "redirect" calls received locally over a POTS line, allowing cheap long distance and international calling from any phone line. However, the wording of the article doesn't make this at all clear. | |

Truphone offers tons of free calling options, and is great when you're in a WiFi hotspot. It works just like your mobile phone on a mobile phone and the set up is painless. Right now it works on Nokia E series and N95, N80 IE, N81 and a few others.
