are full duplex SOUND CARS required for voip to be used EFFECTIVELY in a call center?

A half duplex sound card can only output sound or input sound at different times. Whereas a full duplex sound card can do both at the same time making it ideal for telephone conversations or VOIP Voice over Internet Protocol. Half duplex cards are not suitable!

If you mean on regular POTS (plain old telephone system), you must have a V.92 modem, AND using an ISP that supports V.92 interrupt, AND have call waiting. As for HOW you answer, that would depend on the modem.

OK - I podcast, just wrapped my 160th show. I use a Plantronics Computer headset. Key is to position microphone 3 fingers away from your mouth, not under your nose. I think it was $14 from Fry's\n\nFor calls, I use a Radio Shack call recorder, plugs in between your phone and headset (phone must have headset jack). Was $24.\n\nProcessing your voice afterwards helps: normalize, use a little reverb, and compress. It makes a big difference, and you dont really need to use hardware to do it. \n\nThats the cheap method. You can spend a lot more and there are huge differences and situations. It depends on where you will be using it, who you will be talking to. Big difference between say a portable , interview show, and/or studio.

yes.\nOpen the "Actions" menu and click "Call Setup" to open the "Call Setup Assistant." Follow the instructions on the screen to test your sound system. \nhttp://search2.cc.dcn.yahoo.com/cct_search.php?brand=yahoo&ui_mode=answer&prior_transaction_id=259057&action_code=5&highlight_info=16787547,66,77&turl=http%3A%2F%2Fhelp.yahoo.com%2Fl%2Fus%2Fyahoo%2Fmessenger%2Fvoice%2Fvoice-47739.html&answer_id=4429781#__highlight

Yahoo messenger has free p.c to p.c calls.  A microphone helps, but even if you don't have one you get fairly good sound.

It is all of the interface required to make a VoIP phone work.  If you do not want to use their official box, you can also purchase one of your own.  Most networking companies sell routers with built-in VoIP capabilities.

Depends on PSTN network you have, That PSTN switch should have an extension for VoIP and you have to see if those analogs are compatible with PSTN. Please reply with more details.

you sure can but you can't use things like vontage but to talk on head phones or a mic you can call PC to PC with dial up it will just take a little longer to connect

You can get loud or visual remote ringers (flashing light) from places like Radio Shack. All you have to do is run a phone jack into the area that you want the ringer and plug it in (the remote ringer may also need an AC outlet for power or be battery operated). Another option is to get a cordless phone and carry the handset with you. That way if the phone rings it will ring on the handset and you won't have to run to get it.\n\nIf you really want to use your PC, you'll need a fax-modem with speaker-phone capability. The speaker-phone function will do the ring sound via your PC speakers. This will also require a phone jack near the PC to hook the modem to the phone line.

not unless u have a telephone network setup not via the standard telephone lines, so the simple answer would be No since u would need some good hardware to do what your suggesting.

You need a voice modem to make calls with your computer that will work both ways. Also, you need special phone calling software. Try http://www.voicecallcentral.com/

Voice over IP began as the result of work done by some hobbyists in Israel in 1995 when only PC-to-PC communication was available. Later in 1995, Vocaltec, Inc. released Internet Phone Software. This software was designed to run on a home PC (486/33 MHz) with sound cards, speakers, microphone, and modem. The software compressed the voice signal, translated it into voice packets, and shipped it out over the Internet. The technology worked as long as both the caller and the receiver had the same equipment and software. Although the sound quality was nowhere near that of conventional equipment at the time, this effort represented the first IP phone. \n\nBy 1998 VOIP had reached some potential. A number of entrepreneurs started setting up gateways to allow first PC-to-Phone and later Phone-to-Phone connections. Some of these entrepreneurs started by providing customers a facility to make free phone calls using the regular phone. Every phone call which the user made had an advertisement at the beginning and at the end of the call. This service was only available to users in North America. This service allowed the users to make free long distance calls. This “free to the customer” marketing model, was sponsored by various advertising companies or agencies. These services often required the services of a PC to originate the call, although the actual communication was from ‘phone to ‘phone. At this stage, VOIP traffic represented rather less than 1% of voice traffic. \n\nIn 1998 three IP switch manufacturers introduced equipment capable of switching. At present, most IP switching and routing equipment suppliers offer VOIP as either a standard or as an option on their mid-range and up equipment. VOIP traffic exceeded 3% of voice traffic by 2000, and is forecast to grow rapidly to between 25% and 40% of all international voice traffic by 2005. Today there are two standards for VOIP switching and gateways: SIP and H.323. The former primarily relates to end-user IP Telephony applications, whereas the latter is a new ITU standard for routing between the circuit-switched and packet-switched worlds used for termination of an IP originated call on the PSTN, but the converse is increasingly becoming common.\n\nVoice is the latest core function making its way into the IP world. In the years since VOIP has been introduced, a growing list of technology providers have begun to offer PC telephony software. There is a spate of gateway manufacturers entering the market. Until recently, VOIP provided PC-to-PC telephony primarily over intranets typically found in a business environment. With the introduction of gateway infrastructure outfitted with VOIP technology, users can now look forward to the widespread increase in the usage of Internet telephony.\nPre VoIP Project history\nThe project first started with evaluation of Voice over ATM because at that stage VoATM was available as well as standards, and vendors did not have available VoIP products.\n\nThe VoATM started with using ATM to provide a dedicated Permanent Virtual Circuit (PVC) data pipe between two PABXs, nothing more sophisticated than glorified Time Division Multiplexing. A report was completed for this part of the project.\n\nThe next step would have been to look at ATM switched virtual circuits (SVC) but Jonathan Potter of CSIRO supported and resourced a move to the emerging VoIP technology. A significant driver for this was the fact that ATM was not ubiquitous (did not extend to all locations) and was not likely to do so, but IP did have full reach and thus large potential.\n\nPhase 1 of the VoIP project: early 1998 to 1 October 1999\nThis phase was to get the VoIP technology working and to test it in a large pilot between PABXs. During this phase Cisco provided significant support which was to the mutual benefit of Cisco, CSIRO and AARNet. This phase was completed on 1 October 1999.\n\nKey successes of this phase:\n\n\nVoIP from PABX to PABX became fully functional, as indica

If all lines may be in use at the same time, you probably need a T-1 line.  If you're going to have six phone lines, your best bet is an integrated T-1 provider that uses VOIP technology.  \n\nThis way, they will terminate all six of your lines into a punchdown block which can use standard phone jacks or plug into a system.  This way, you'll only have one box for all of your VOIP lines instead of having a box for each line.  Plus you'll get the benefit of having the T-1 line + the six phone lines on the same bill.\n\nCheck out http://metrot1.com/content/view/47/62/  for pricing information.\n\nThe reason you need a faster connection is because VOIP uses up to 53k PER line.  Therefore, if all six lines were in use, you'd be running 318k of your bandwidth in phone calls.  Most DSL and cable providers advertise UP TO 384k in upload bandwidth but typically run closer to 280-300k.  You wouldn't have enough bandwidth to use both internet and phone.

Lots of phones have build in caller i.d. now-a-days.  I'd say yes, that most offices have that service.  HOWEVER, lots of chains and other businesses aren't allowed to use it for callback purposes.  Daycares, government offices and womens shelters, for example!

If you can use Skype as your VOIP software, there actually exists such phone which can fulfill all your requests.\n\nSee the phone link at here: http://www.amperordirect.com/pc/b-rtx/internet-phone-dualphone.html

don't know quite what you mean but here it goes for phone calls use VOIP like vonage, and conferences use Your PC for conference meetings over the net Thats gotoyour pc  https://www.gotomypc.com/tr/KimK/2006_Q1/120x240_pvia_new/g25KIMlp?Target=mm/g25KIMlp.tmpl
