With each of us carrying around a phone in our pockets, it’d be easy to forget that desk-based phones still play a vital role in business operations for many companies, particularly contact centers.

Traditionally, enterprises have relied on legacy systems like PBX’s to connect them and power their employees’ desk phones.

But, as with all things, time and technology march forward, giving way to new options, like SIP trunking. As awareness of SIP trunking and its benefits grows, more enterprises are starting to evaluate moving their telephony to the cloud.

So what are the main factors driving the movement away from on-prem PBXs? Glad you asked. Here are five big reasons enterprises are making the move to SIP.

SIP is Mobile

Traditional phone systems rely on copper wiring to transmit signals and, as a result, are physically tied to a location. SIP, on the other hand, uses Internet connectivity allowing you to take your phone (and phone number) anywhere you have an internet connection.

This is ideal for enterprises that rely on a remote workforce, as they can provide employees with a company telephone number that their employees can use wherever they’re located, the perfect setup for distributed call centers, sales, or support teams.

SIP is Scalable

Your telecom needs can change quickly. You may need to quickly add or reduce the number of phones you’re managing. With SIP that’s easy. You can scale up or down as your demands change. This is perfect for enterprises with seasonality that don’t want to be locked into a fixed amount of usage.

SIP is Visible

Because of how SIP is serviced you can have better visibility into how your voice services are being used. Call times, call volume, and other usage data can be used to better allocate resources, allowing you to ensure your enterprise has the available resources when needed, or can easily scale back when demand subsides.

SIP Costs Less

Nobody likes to pay for things they don’t need; with SIP you don’t have to. There are a lot of ways where SIP can help cut costs — only paying for the usage you need (that scaling thing we talked about earlier), being able to send more calls on the same amount of bandwidth versus a TDM circuit, savings on hardware costs by going to the cloud, and even saving on desktop phone costs by having calls sent to PCs or mobile phones. That’s a lot of ways to save, and who doesn’t like to save money?

SIP is Flexible

You’ve probably heard the term “elastic SIP” thrown around, and there’s a reason for that. Because SIP traffic is sent over an Internet connection you can use it in flexible and creative ways. Embedding SIP into your software and application infrastructure is the exciting new way, but enterprises are finding new and innovative ways every day to solve for voice needs that a legacy PBX system just can’t manage.
