How to Upgrade Your PBX at a Low Cost


Your business is growing faster than you could have ever imagined.  In just a few short years, you’ve gone from 5 employees to 50, and you have branches in multiple locations, some of which are international.

In the midst of this expansion, one thing is painfully clear: your aging phone system isn’t doing you any favors.  If you’re going to keep growing at this rate, you need to know how to upgrade your PBX at a low cost and protect the investment that you made in your existing phone system.

Sound familiar?  If it does, don’t worry.  Lots of growing businesses are beginning to realize that they can cut costs and gain added functionality by connecting their legacy phone systems to the cloud with SIP trunks.

In this article, we’ll discuss some of the core benefits of SIP trunking, and explain how to upgrade your PBX at a low cost with this service.

Benefits of Upgrading Your Existing PBX

Save Money on Your Calls

SIP trunking allows your business to use VoIP service and save money on inbound, outbound, and even international calls.  In fact, this is often the biggest reason that businesses choose to connect their traditional PBX to the cloud.  You can also easily connect phone systems across your different office locations, allowing for one, unified, cost-effective phone system.

Grow Your Business Cheaply

As your company grows and your call volume changes, you can simply add SIP trunks as needed to support additional agents.  And because your phone system is already connected to the cloud with a SIP trunk, you won’t have to purchase additional hardware as you scale.

Maintain Business Continuity

No matter how big or small your business is, every call is important.  When you upgrade your existing PBX with a SIP trunk, you’ll have the assurance of failover and automatic call rerouting procedures.  That means that you won’t have to worry about missing calls, even in the case of natural disasters or other unforeseen issues.

How to Upgrade Your On-Site PBX

If your business currently uses an on-site PBX, you’ll need a VoIP gateway to connect it to the Internet.  Also known as an Integrated Access Device (IAD), this piece of hardware converts phone traffic from the PSTN into digital packets that can be transmitted over the Internet.

In order to connect your existing phone system to the cloud, your VoIP provider will simply install the IAD between your router and PBX. This allows you to keep your PBX and phone configurations, so you won’t have to purchase any additional equipment.



How to Upgrade Your IP-PBX

If your PBX is already IP-enabled, then the process of upgrading your legacy phone system is even easier.  Since your phone system is already connected to the Internet, no additional hardware is required.  Your VoIP provider will simply configure a SIP trunk to connect to a traditional PSTN network, allowing you to make long distance and international calls for a fraction of what you would normally pay.
