Please provide a brief overview of what the purpose of a SIP gateway is, and how it can be used.
Yes that's pretty brief! What I want to understand is - I presume it's bidirectional? It also routes voice back to a SIP server. And the phone it connects to - what sort of phone can be used?

There is no question about it - VoIP is fast becoming the telecomms technique of choice for home telephone service. For the general public, it is no longer a matter of 'IF' you'll switch to VoIP net telephone service, but when. The amount of VoIP customers in America increased over 150% between 2005 and 2006, and now about 10,000,000 homes use net telephone service. The sole duty for home VoIP service is a broadband ( fast ) web connection. Conmen can hijack calls and pretend to be client service members to gather private account info.

But keeping all information inside VPNs comprises extra hardware and software costs. Hackers may procure access to an open port and re-sell mins of your company's VoIP account. To stop these issues from creeping up, your service supplier must continually monitor VoIP service use watching out for strange activity or packet routing to states with few known clients. Create and maintain powerful relations with account representatives. Even after hiring a voip service, it is critical to make sure that you receive enough and increased security that will handle more recent safety threats over the web. VoIP providers just need to maintain a room full of servers and switches, web connectivity and a staff of technicians to provide patrons with prime quality net phone service. Web telephone service depends on a broadband net connection to route calls around the globe Wide Web, to anywhere in the world. If you truly want to save a ton of cash on telephone service, consider employing a VoIP supplier that offers a limitless yearly plan. Most VoIP suppliers also throw in tons of free telephone features too - like caller ID, call waiting, voicemail and call forwarding - simply to name a couple.

Most VoIP plans give you unlimited local and international calling inside the US, Canada and Puerto Rico for rather less than $25 a month. Some VoIP suppliers supply an yearly 'prepaid' plan that costs roughly $199 a year - this is the best worth for the cash. Most VoIP providers give you tons of free calling features like call waiting, call forwarding, caller ID, voicemail and more. The correct way to Install VoIP Net Telephone Service Once you've decided upon a VoIP service supplier ( there are plenty of to make a choice from ), join up to service on their web site. If your buddy is offline but has turned on call forwarding you can reach them when they are away from their PC. Downsides Using your PC to make and receive calls implies it has got to be kept 'on ' just about at all points, unless you purchase a 'stand-alone ' telephone that connects right to your net connection and has the 'VoIP ' software. Long-distance calling : With this feature, you can call long distance to several states. Calling the 911 number with your broadband telephone is not practical so you'll need to use an alternative service for it.

I like to know how to add VOIP (pc/phone to pc/phone) calling facility to a web page. I did some reading and leant some theory about the protocols, gateways, Gate keepers etc. But I was unable to find out answers to basic questions like

1) Who are the Gatekeepers who can sell me a SIP username.
2) From where do I get the SIP username and Passwords needed to connect to a SIP gateway?

3)Do I need to have my own Gateways or can I use a third party gateway for a fee, if so where can I find one?

Thanks in advance,

Axell.
