When any kind of VoIP service is mentioned, it is hard not to mention SIP. SIP is one of the main set of rules that defines how data related to VoIP communications will traverse the internet. SIP works on top of the Transport Layer as an independent, higher-level application protocol. Utilizing SIP for network transmissions, like VoIP services, is one of the most secure and reliable methods of connecting and communicating through the internet.
For the most part, web pages are designed to use HTTP or HTTPS to establish a connection between your device and the web server. SIP functions in a similar manner ? creating a secured end to end connection for the sake of reliably transmitting data packets associated with VoIP services. Your communications will take place over the internet rather than across on old analog telephone service.
Phone services from telecom providers will eventually require additional, costly upgrades to a company?s existing physical phone network. When additional lines are purchased from a telecom provider, the lines are ?trunked? as a bundle to your business. SIP trunking utilizes the same concept to expand your phone connections, however it is accomplished virtually. When a new phone is added to the system, it simply has to connect to the network ? the administrator that manages your phone services takes care of the rest.
Utilizing a SIP phone on VoIP has numerous advantages, especially when compared to traditional phone systems. VoIP can be utilized for large scale voice and video conferencing at a much lower cost than regular phone services.
SIP phones offer such benefits as:
- Companies typically see a quick ROI as the TCO of VoIP systems is much lower across the board than traditional telecom services. Older systems made use of analog signals, transmitted at low bandwidth across several switching stations until a connection is established. VoIP circumvents this process, almost entirely, as VoIP utilizes the internet to establish a much more reliable connection. Using a SIP phone only requires a monthly premium to utilize the internet for telecom services and beyond, eliminating the need for a traditional phone system altogether.
- The applications you utilize for unified communication purposes use SIP phones. Traditional phones cannot be used to directly integrate into robust VoIP software which grants SIP phones greater capabilities than a standard phone. ?A VoIP phone can use the network to power high volume conference calling, as well as transmit audio directly over the internet through appropriate services. The IT staff managing the in house network or the hosting service can monitor connections, adding a layer of security in your company.
- Scalability in not burdened by physical installation and additional costs from a telecom provider. When new phones need to added to the system, it simply needs to have access to the network. Administrators integrate the new phone into your existing network without incurring any additional cost to your service.
