On-Site vs. Hosted IP PBX Systems

In the same way that traditional telephone lines require PBX Systems to switch telephone calls, VoIP systems require an IP PBX system to connect IP Phones to the Public Switched Telephone Network (PSTN) and complete phone calls. Unlike traditional PBX systems, IP PBX systems utilize the TCP/IP protocol to deliver audio, video, and instant messaging.

When setting up a VoIP system, network administrators need to consider the benefits and limitations associated with IP PBX Systems and hosted PBX Systems. Businesses need to take into consideration their company size, familiarity level with IP PBX systems, and the time and resources they’re willing to invest in maintaining the equipment to determine which option is the best fit for their company.

Bring us your phone number or choose your own

SIPStation allows you to select new numbers or bring your existing phone numbers with you – a service called porting. For more details on porting please see the following page:http://wiki.freepbx.org/display/ST/Number+Porting

SIPStation gives you the freedom to select as few or as many numbers as you need. If you need one inbound number, also known as a DID, you can have all your customers call that number and then use an IVR (Interactive Voice Response) to allow callers to dial an extension or a business function like sales or support. If your business requires you to use a public number to advertise, no problem, it’s easy to associate an inbound number directly with an extension. The caller will be routed directly to the extension.

Of course, it’s no problem to mix the two and have some users with DIDs and others accessible through an IVR

On-Site IP PBX Systems VS  Hosted IP PBX Systems

On-Site  IP PBX Systems

On-site IP PBX systems remain on the premises of a Local Area Network (LAN) of an end-user. Typically, medium-sized to larger enterprises find investing in an on-site system appealing because it gives them direct access and control over their Voice over IP (VoIP) system, including how many extensions to add to a network.

Though on-site IP PBX systems are customizable, they do not come without their limitations. Network administrators are responsible for updating and maintaining their hardware.  Should the hardware fail, businesses will absorb the costs.Start with the customer – find out what they want and give it to them.

Hosted  IP PBX Systems

Hosted IP PBX systems offer a maintenance-free solution that will bring the VoIP benefits to a workplace without the hassle of maintaining and updating the equipment. The off-site solution eliminates the need to purchase or upgrade hardware. Hosted IP PBX systems are ideal for small to medium-sized businesses. Hosted systems  are ideal for telecommuters  in different locations and that require access to a business phone.

With a myriad of vendors, it’s important to take into consideration the history and performance of a company before choosing them as your host.Oftentimes, the quality of your communication will depend on the service provider.
