Session Initiation Protocol (SIP) allows you to increase efficiency and reduce costs; however, not all SIP implementations are equal. Some use the public Internet, while others transmit via a private network. Which one is right for your business? That will largely depend on the type of work you perform, the size of your company and your budget. Below is some information that will help you decide.

Public Network: Bring you own Bandwidth

When using a public network, your business will provide the bandwidth for each call. The SIP provider then utilizes this bandwidth to make the connection. This is the most affordable option, which is why many small businesses choose it. When calls are transmitted over the public Internet, your maintenance costs are reduced as well. Even so, your odds of a dropped call increase, and you may be prohibited from porting your number if you change providers. The amount of outbound and inbound data traffic on your network can also negatively effect your call quality.

Private Networks: Carrier or ISP Provided Solutions

Private networks prevent devices outside them from “seeing” or communicating with computers that are on the network. In this scenario one carrier typically provides a secure link from your site to the providers core network with internal traffic segregated via IP provisioning such as vLans. As such, private networks are far more secure, and recommended for businesses that must be HIPAA, Payment Card Industry (PCI) or Sarbanne-Oxley Act compliant. Having a private network is more expensive; however, it is nowhere near as costly as the fines and penalties associated with non-compliance are. Since the bandwidth and SIP provisioning are managed by one carrier, Quality of Service (QoS) and Class of Service (CoS) are guaranteed in most scenarios, which provides exceptional call quality and reduces other common issues such as network congestion.
Generally speaking, if you are concerned about security, a private network is best. On the other hand, if you do not handle sensitive information, using a public network might be fine.
