Talk:Voice over IP

message: Before anyone bites my head off I would just like to mention that I am a telecoms professional with over 22years experience in Legacy AND IP Communications.
Please refer to the Eupac IP Network Solutions site [] for a lovely simplistic description of the difference between the two.
"Yet it is important to distinguish between VoIP, which is a digital transport vehicle for phone calls, and IP telephony, which is a digital phone system based on internet standards.  This is important, because business stands to benefit from both VoIP and IP telephony – in substantially different ways. VoIP is a method of digitising your voice so that it can be transmitted across the Internet to save call charges.  Whereas IP Telephony is a way of digitising your  phone system so that it can leverage the Internet, your computer, and your other business software applications (CRM, CTI, Outlook) to increase productivity within the Business.  VoIP is actually a subset of IP Telephony."
Or put even more simply:
- IP Telephony is the carriage of telephone calls over IP based networks.
          o Voice quality target is telephone call quality, no better, no worse
          o Attempt at making calling procedure and dialing same as PSTN
          o Attempt at supporting various PSTN features and functionality
- VoIP is the carriage of any voice signal over IP based networks.
          o Voice quality can be designed according to the applications need.
          o Design for features and functionality as needed by the application
          o Next step to Multi-media over IP
          o Definition can be extended to include all audio, e.g., music
Some of us "dinosaurs" have been around long enough to know where both technologies began, where they came from and where they are going ;-)

thread_title:  VoIP is not IP Telephony (although they are similar!) 

message: The previous content wasnt correct:
→VoIP systems usually interface with the traditional public switched telephone network (PSTN) to allow for transparent phone communications worldwide.
I replaced it with the definition from International Engineering Consortium. Klapouchy (talk) 22:43, 27 April 2009 (UTC)
thread_title: Definition in the Introduction section

message: The article reads:
:An advantage of using a softphone with a VoIP service provider is the ability of having a fixed phone number which can be moved to any country or location (This is also possible with ATAs and VoIP phones, although it requires the physical relocation of the hardware.)
Any voip solution is identical in this respect: they are agnostic about their geographical location.  You don't have to physically relocate a voip phone or ATA to enjoy these advantages.  You can alternately just use a second ATA in a second location.  And a softphone is no different: you have to either relocate your computer or install the softphone on a second computer.
So I'm deleting the sentence. -lethe talk [ +] 01:58, 17 July 2009 (UTC)

message: The voice codec is not the primary reason of fax transmission failures.  True, if you're using something highly compressed such as g.729, but as long as you're using G.711 - a or u law, which is the exact same codec as used in the PSTN.  The problem with faxing over common internet based VoIP providers is the packetization of the internet.  That along with your call audio getting handed off to distant wholesale provider's PSTN interconnets over the internet, and with many routers along the way to the PSTN interconnect don't always provide good enough QoS.  Some very good VoIP providers do the PSTN coversion in-house so that your calls are sent to the wholesale provider off-internet, so providers like these can provide very good QoS.  66.114.93.6 (talk) 11:39, 10 January 2011 (UTC)

Why just 2004? Have they not proliferated in other years? This historical milestone, or at least the date to which it is confined, seems rather dubious to me.  —Preceding unsigned comment added by 130.14.254.26 (talk) 20:24, 21 January 2011 (UTC)

message: VoIP or Voice over internet protocole also called internet telephony enables users to speak to other users over the internet. That is VoIP uses the internet (instead of the public switched tgelephone network) to connect a callling party to one or more local or long distance call.  —Preceding unsigned comment added by 119.152.80.81 (talk) 14:41, 1 February 2011 (UTC)
replies: text: Actually, no.  When first coined, we used the term to refer to carrying voice over IP for some leg of a call: at that time typically through a modified PABX to a private internet gateway plugged directly into the PSTN over PBX trunks. — Dgtsyb (talk) 22:04, 1 February 2011 (UTC)
replies: text: I think part of the problem is that this article has been reworked bit-by-bit since 2002 without a major, unifying overhaul. As technologies converge, the technical and popular distinctions between IP telephony and consumer VoIP are growing faint. As the ILECs extend fiber networks throughout the middle mile and, in some places, the last mile, people with "analog" or PSTN POTS phones really only have copper until it hits the little box in their backyards. The national trend is moving towards an all-IP network, in which case "VoIP" will be nothing more than a telephony service provided by the non-LECs and IP telephony will be anything provided by the RLECs, CLECs, and ILECs.

message: The header of this article lists "Comcast Digital Voice", which is a blatant advertisement by Comcast. VoIP protocols are utilized by many companies and this article should remain neutral where patents are not a consideration.

replies: text: The hatnote is there because the article about Comcast's VoIP product is at Comcast Digital Voice – even though the product was called Digital Voice – Digital voice redirects to Voice over IP. Looks like the product is called Xfinity Voice now. --Pnm (talk) 05:25, 10 February 2011 (UTC)
replies: text: I'd like to remove the hatnote, it is commercial and confusing to readers (and probably some editors too). Easiest thing to do would be to point Digital voice to Comcast Digital Voice. I'm not familiar with the use of digital voice as a synonym for VoIP. --Kvng (talk) 15:52, 11 February 2011 (UTC)

message: I was wondering whether analog to digital telephone conversions may be mentioned in this article. A notable project is OpenUSBFXS, see also http://code.google.com/p/openusbfxs/
Some things I don't get on the project though:
* is the old telephone number kept (ie 00 33 51 123456 or something like that; 00 --> prefix, 33 --> country code, 51--> area code, last 6 numbers the actual phone number OR
does a entirely new (VOIP) telephoen number needs to be taken ?
* is the data tranferred via the old telephone line (POTS) or via a seperate internet access line (ie 56k, ISDN, ADSL or even cable, ...)

message: Very good informative article so please excuse me for the tiniest of nits.
"Premise" should be "premises".  I know that using "premise" this way has become the technical vernacular, but it grates a bit.
The article takes care to define acronyms at the first use but there are a few exceptions (DSL, ADSL, QoE, PBX (although identifying PBX as Private Branch Exchange may not add clarity), PVC and TCP).

message: In addition to the given statements under the "pronunciation" section, I knew a French-Canadian guy for whom French was his native tongue, and he would pronounce it "vwahp" ("-oi-" is pronounced something like "-wah-" in French.) Should a note be made in that section about this?  — Preceding unsigned comment added by 97.115.28.10 (talk) 01:42, 7 August 2013 (UTC)
replies: text: Yes, I think a pronunciation note will be ideal because the "vuáh" pronunciation is not only used in French-speaking Canada but also in France, where it would be "voix sur IP" (pronounced "vuáh sur I-Péh", the word "sur" pronounced the same as the Spanish word meaning "South" and the letter "I" pronounced not as in "iPad" but as in "machine" or something like that, I'm not good at phonetic transcription) --Fandelasketchup (talk) 11:02, 12 November 2016 (UTC)

message: reference 85 relates to the milestone from 1991 regarding the release of "Speak Freely".
it references the speak freely site which claims to have released in that year.
Should there be outside sources claiming that speak freely was indeed the first VoIP application or is their self claim enough?  — Preceding unsigned comment added by 144.160.228.103 (talk) 18:48, 4 March 2021 (UTC)
