Forward Virtual Numbers How it works and passes PSTN?

How virtual numbers diversion works and what PSTN forwarding?

It is easy to set up a virtual phone number in many different countries around the world. Dozens of vendors services already offer this feature. A virtual number, often called "DID number, not associated with subscriber line specific. The DID can be delivered to their remote destination - more often for some type of VoIP and SIP, H.323 or IAX2 - despite coming from another country.

For usually DID are fixed numbers, but the toll-free (toll free), mobile number and the premium can also be delivered to your virtual numbers through VoIP.

Suppose you run a shipping line in Boston and his company maintains a large overseas base in Glasgow. Instead of having to European colleagues make a number of U.S. every time they need to reach your home, your company can install a number UK DID (virtual number) to ring in Boston.

UK dial +44 141 XXXXXXX U.S. location rings

When the number +441411234567 UK brand, IP-enabled phone in the U.S. rings and the call is local to the caller.

Continuing with our example, there is a number of devices that can be placed on the receiving end (Boston) to answer the call.

Some of the phones hardware (called ATA, analog adapters phone) are: Linksys (Sipura), Grandstream, Snom, Cisco Systems, Avaya, Dlink and others. These devices are connected to the broadband connection and receive phone calls to DID numbers via the Internet. Most of these are based on SIP ATA, while H323 and IAX2 devices even exist.

You need your own IP infrastructure to record the phone or use some of the free SIP providers will give you a SIP account or SIP address (URI) to receive IP calls a. Some of these providers are: Gizmo, VoipCheap, Sipgate, Callcentric, BroadVoice, FWD. You can also use their softphones (software simple for your PC or laptop) to answer calls on a computer.

DID numbers may also be referred to other VoIP networks. For example, Skype DIDlogic.com provides forwarding for DID number. If you have Skype installed on your computer, you can add an incoming number (Skype also offers the same feature, called-in for Skype however, the service is not available in many countries).

China was marking his 86 XXXXXXX Skype software rings

Since Skype is free to use, numbers can also receive free calls from any place in many countries with Internet access - Skype. account DIDlogic , For example, offers DID numbers in Australia, Bulgaria, China, Iran, Israel, Latvia, Lithuania, Pakistan, Poland, Russia, South Africa, Thailand, United Kingdom and the United States.

Invites its DID number can also be sent to your Google Talk, MSN Messenger for free.

Israel 972 XXXXXXX was marked sounds of your favorite software

If you travel a lot, DID numbers forwarded to your VoIP software can save money. If you purchase a DID number in Australia, for example, can receive calls from his home in the number of Australians with anywhere you have available broadband (public Wi-Fi, Wi-Fi in the hotel or any other hotel or guest Internet access). As a matter of fact, you do not even need a fast Internet connection. You can implement its VoIP software in just 80 kbit / s line and still have a high quality conversation. That is slightly over a dial-up modem access good phone. Just to be stable. Therefore, if you are in, say, Thailand and there is no decent internet access, you can fire up your Google Talk or Skype or receive calls by DID number at no extra cost to you.

Sometimes, however, you do not have access to your computer or Internet access is not functioning or unusable. In this case, you need PSTN forwarding. This option can also provide significant savings if the installation correctly.

What is PSTN? An acronym for public switched telephone network. The term used to refer to analog lines and traditional phone systems, but in the context of virtual numbers, PSTN really means "just a normal phone number, number of actual phone, another real phone number. "

So in case of virtual numbers, deflect and follow-me service, "PSTN" is just "another line with a real phone number."

For example, the virtual number in China that follows is a DID everywhere.

You can send it to Skype, SIP device or software, Google Talk or any other service that uses VoIP. You are sending your DID to a target IP.

However, if no Internet connection is available, you can send your DID to another phone number anywhere in the world - to your cellphone, for example. Or your phone number fixed in another country. This is more of a destination PSTN.

Forwarding virtual number in Moscow, Russia, for example, a phone U.S. Cellular is PSTN forwarding:

Russia DID 495XXXXXXX marked U.S. No. 7 +12135551212 mobile real ring

Divert to PSTN not usually free. Some companies can charge very high rates per minute for this service. Others charge a certain minimum monthly fee to provide a package of minutes to several destinations in the world. European mobile calls can be especially expensive since all incoming calls are free for mobile subscribers in Europe, and pays caller.

Not all DID providers allow you to send your virtual number to PSTN. Those who can collect a large quantity minute!

- $ 0.60/min to Swiss mobile

- $ 0.35/min to Spanish mobile

- $ 0.15/min to Russian mobile

- $ 0.05 to landline (fixed) numbers in the U.S., UK and EU

Today, the above rates are very expensive. Do not pay in 2009. This is virtual number because many providers add to the price when they buy the minutes of long distance carriers and sell it to you at a premium. Some providers, however, only has to give the user the same wholesale price operating costs. This is what the previous destinations MUST effectively -

- $ 0.15/min to Swiss mobile

- $ 0.09/min to Spanish mobile

- $ 0.03/min to Russian mobile
