Session Initiation Protocol (SIP) is a new generation protocol that is fast gaining popularity in the VoIP technology scenario. SIP enables many of the traditional features while also bringing in new facilities. As SIP is an internet based protocol, it can work seamlessly along other internet protocols. SIP also allows establishing the user location, which is helpful in emergency services.
SIP and PBX
SIP is designed to work with Private Branch Exchange, which is touted as one of the biggest advantages of the protocol. As we know, PBX enables users within an office set up share a certain number of outside lines to make outgoing calls. PBX brings cost benefits to the company by limiting the number of lines it needs. SIP can enhance this further by enabling free long distance calls to all parts of the world. As SIP is internet based, the cost of calls can be as cheap as an email which is to say it is free. SIP and PBX working together bring free interoffice as well as long distance communications.
Set up and transaction costs also come down with SIP. The phones can be physically moved without rewiring and set up costs. It also does away the need for complicated hardware and software. The peer-to-peer structure of this system makes it possible for the users to plug into any available broadband connection to make and answer calls.
Save on your Hotel Bills
SIP brings benefits in unexpected areas too, like saving on your call bills from a hotel room. These charges can be exorbitant especially when the calls are long distance, or when in the conference mode. These charges can be of a serious magnitude for companies that need many of their employees traveling or operating from different locations across the globe.
SIP can solve this issue very effectively. Just like an email, it does not matter whether you are calling a local number or a number in another country using SIP. Since SIP calls are made through the internet, SIP users can make free calls from their office, home or even a hotel room- in short wherever a broadband connection is available. And just as sending an email can be sent to many recipients at no extra cost, conference calls become available at no extra cost. All this means that companies can now easily have their employees keep in close touch no matter where they are, without having to pay a fortune for it.
As SIP has peer-to-peer connections, the company can also enable their hundreds or even thousands of employees make SIP calls. Consider the costs for such a situation under traditional telephony. On the other hand when SIP and PBX work together, the structural costs remain the same while the company expands its business.
SIP offers users huge cost savings over traditional telephony in multiple ways. With SIP, users have the flexibility to make calls from any part of the world and at any time. Within the facility set up, the user company can expand its PBX system using SIP without incurring extra costs. There is no need for complicated hardware or software, so the implementation process is simple. Considering the huge benefits, it will be just a matter of time till customers wake up to the possibilities of SIP.
