SIP trunking is something that has really attracted my attention as of late and I cannot read enough about it when time allows. If you follow this blog, Facebook or Twitter page, you already probably know about my recent fetish. I have posted some private label rights articles, republished articles from other websites where sip trunks are explained.

Recently I shared an article about SIP trunking security from http://www,networkworld.com, in which one person who left a comment felt that a business needs to treat their SIP trunk provider like they would any other public network. Most definitely agree and second that. You may be asking; “So do you need a business to use and take advantage of SIP?” This also applies to mobile devices like the iPhone and iPod Touch. You can even turn an iPod Touch into a SIP phone with the right application. However, keep in mind, this type of SIP phone is not completely secure and sometimes require you to share your SIP credentials with a 3^rd party. Your choice, ensure you look into the security precautions and what your provider and 3^rd parties require in regards to credentials and other information.

A Session Initiation Protocol (SIP) trunk is a service that businesses use for live communications including VoIP (Voice over Internet Protocol). It enables communication with others, outside the enterprise, over Internet Protocol by connecting the SIP to a traditional phone system. It is also very convenient as it helps in creating a single means for voice, video and data by externally connecting an IP phone system through SIP trunking, in lieu of the traditional phone system. But this can only be used with an installed PBX. Hence this service is slowly but surely gaining popularity, because of its cost efficiency and convenience.

3 main components:

IP PBX: The main function of this component is that it allows connection and communication with all endpoints over an IP network. It can switch calls between a VoIP connection and a traditional fixed phone, as well as between two traditional fixed services.

ITSP:Internet Telephony Service Provider ensures connection of the traditional phone system from an IP network. Also, it helps to transport IP communications across an IP network.

Border element: The internal VoIP network, traditional telephone system and the external IP carrier are all connected with the help of this border element. This is usually of two forms: either a switch that transfers calls between the phone system, or it can also be a firewall which is SIP-friendly.

But how does it work?

For example, you need to call a client of yours who is in another city. So you call your client in the same manner as you do now, and your call gets converted to an IP call before leaving your office. This IP call then travels over the IP network provided by your service provider. And before it reaches your client, the call gets converted back to the traditional phone system, and your client receives the call just like a normal fixed line call.

It essentially converts both data and voice into a single conduit. It lets the data network carry voice traffic by transfiguring between the traditional fixed phone and the company’s Internet connection.

Benefits

This service is considered to be really beneficial for businesses. Here’s a quick look of the numerous advantages it brings to businesses:

• Doesn’t require a costly TDM-gateway infrastructure to be purchased.
• It eliminates the need to purchase costly equipment to convert data between the traditional phone system and the IP voice.
• Monthly expenditures are reduced considerable as there is only one voice and data connection.
• Outsourcing the connectivity of the traditional phone system is now a definitely possibility, and results in saving money.
• The benefits of the VoIP can now be used, without compromising on the traditional phone system.
• As a whole, it is considered to be really cost efficient, and is a good long-term investment.

Hence this SIP based technology is a great boon for businesses, especially those that need to constantly exchange audio and video data to others in other parts of the world.

A Session Initiation Protocol (SIP) trunk is a kind of service using which businesses can use real-time communications such as VoIP (Voice over Internet Protocol). But this service can only be used with an installed PBX. It allows communication over Internet Protocol with others outside the enterprise by connecting the SIP to a traditional phones system. Businesses can also take this to the next level by creating a single passage for voice, video and data. This can be done by connecting an IP phone system externally through SIP trunking, instead of using the traditional fixed phone system. Hence in an increasingly global world that we face today, this service can be really cost efficient and reliable at the same time.

But how does it work?

Lets take an example to understand this better: Say you are a sales representative based in New York city, and you need to call your client in California. So you call in the usual manner, dialing the dialing code followed by the number. The call, before leaving your office, is converted in an IP call and then travels to California over the IP network of your service provider. And just before it reaches your client, the call is converted back to the traditional PSTN.

Hence this service converts both data and voice into a single conduit. It allows the data network to carry voice traffic by converting between the traditional fixed phone and the business’s internet connection.

3 main components of SIP Trunking:

IP PBX: Connecting and communicating with all the endpoints over an IP network is the main function of this component. It switches calls between a traditional fixed phone and a VoIP connection, or between two traditional fixed lines.

ITSP (Internet telephony service provider):This component helps in connecting the traditional phone system from an IP network. Also, it helps in transporting IP communications across an IP network.

Border element: usually managed by the service provider, these border elements helps connect the internal VoIP network, the traditional telephone system and the external IP carrier. The border element can either be a switch transferring calls between the phone system, or SIP-capable firewall.

Benefits

SIP Trunking service has numerous advantages for businesses. Some of the benefits that companies get by using this service are:

• No need to purchase a costly TDM-gateway infrastructure
• Eliminating need to purchase costly equipment that can convert data between IP voice and the traditional phone system
• Only one data and voice connection reduces other monthly expenditures
• Companies can now outsource their traditional phone system connectivity to a third party
• Enables making use of the advantages of a hosted VoIP service, without giving up on the services of a traditional phone system.
• In essence, companies can realize a lot of savings by investing modestly in a SIP trunking service

Hence for growing businesses, with a global nature, the SIP based technology can really save costs and increase convenience. It is even far more reliable, and you can realise savings in as short a period as 6 months!

Hence this SIP based technology is a great boon for businesses, especially those that need to constantly exchange audio and video data to others in other parts of the world.

What is SIP Trunking?

An SIP trunk is a logical connection from one point to another via the Internet.

A SIP trunk is simply the use of Session Initiation Protocol (SIP) to set up communication using the net between two parties, i.e. a customer and an Internet telephony service provider (ITSP). The SIP calls are then transferred to the Public Switched Telephone Network (PSTN). As opposed to traditional telephony, there are is no need for physical wires were.

The advantages that Sip trunking offers are as follows:

1. Freedom from BRIs/PRIs/PSTN Gateways

SIP trunking greatly lowers telephone costs by eliminating the need to purchase Basic Rate Interfaces (BRI), Primary Rate Interfaces (PRIs), or local PSTN gateways. Although it is simpler and less costly to extend one’s system over IP, additional hardware costs have to be incurred to move from E1/T1 to two.

2. A SingleVoice and Data Connection

The need for separate voice and data connections is eliminated, the costs go down drastically. Another added advantage is that a single SIP trunking account can handle voice/data traffic for the entire organization. Thus, as the business grows, there is no need to upgrade the infrastructure further.

3. All Calls are now Local Calls

The providers of SIP trunks to businesses, enable firms to outsource their PSTN connectivity to a third party. SIP calls are transferred over the Internet to a termination point which is owned by a service provider. Further the call is transferred to the local PSTN, thus, long-distance charges go down considerably

4. Get the convenience 800 Numbers, but Not the Costs

A SIP Trunking service provider establishes local numbers in specific locations for customers to call on instead of giving them a 800 number. These calls are then terminated locally and placed on the net and delivered to the company’s call center.

Infrastructure Investment Vs. The ROI

For the enterprise, converting to Voice over the net the following investment in infrastructure is required:

• the purchase of an IP-PBXIP Phones or soft clients i.e. those which operate on typical PCs or laptops
• a SIP-aware firewall to maintain security while admitting VoIP traffic.

SIP trunking can generate a reasonably good return on investment. In fact the initial cost of installation might be paid back as soon as six months from installation.

Summary

Thus, even though a small investment is essential before one can avail the benefits from the use of SIP-based communications. However the overall reductions in costs in terms of eliminating the need of Basic Rate Interfaces (BRI), Primary Rate Interfaces (PRIs), or local PSTN gateways and enabling savings on long distance calls, makes the investment more than worth it. To conclude, it’s a robust enterprise solution for telephone bases communication which has huge potential in the coming years in the world of Voice over Internet communication solutions.

Hence this SIP based technology is a great boon for businesses, especially those that need to constantly exchange audio and video data to others in other parts of the world.

These days, all communication technology faces the issue of privacy and identity theft, with Bluetooth being no exception. Almost everyone knows that email services and networks require security. What users of Bluetooth need to realize is that Bluetooth also requires security measures as well.

The good news for Bluetooth users is that the security scares, like most scares, are normally over dramatized and blown entirely out of proportion. The truth being told, these issues are easy to manage, with various measures already in place to provide security for Bluetooth technology.

It’s true that there has been some Bluetooth phones that have been hacked into. Most devices that are hacked into are normally those that don’t have any type of security at all.

According to Bluetooth specialists, in order to hack into a Bluetooth device, the hacker must:
1. Force two paired devices to break their connection.
2. Steal the packets that are used to resend the pin.
3. Decode the pin.

Of course, the hacker must also be within range of the device, and using very expensive developer type equipment. Most specialists recommend that you have a longer pin, with 8 digits being recommended.

Fundamentals of security
The “pairing process” is one of the most basic levels of security for Bluetooth devices. Pairing, is two or more Bluetooth devices that recognize each other by the profiles they share – in most cases they both must enter the same pin.

The core specifications for Bluetooth use an encryption algorithm, which is completely and entirely secure. Once the devices pair with each other, they too become entirely secure.

Until they have successfully paired, the Bluetooth devices won’t communicate with each other. Due to this pairing process and the fact that it is short range – Bluetooth technology is considered to be secure.

As the news has indicated, experienced hackers have developed ways to get around this level of basic security. There are ways to get around this threat, as you can install software to prevent hackers from getting in.

With Bluetooth becoming more and more popular, it’s really no wonder that security is always in question. As Bluetooth gets bigger and better, security will always be something that no one really takes lightly.

If you’ve been concerned about Bluetooth security in the past, rest assured that newer devices will offer bigger and better security. Preventing hackers from getting in is something every owner is concerned about – and the manufacturer’s are very aware.
