SIP Trunks for Business

With BT about to ditch its PSTN and ISDN networks in favour of its new, internet-based IP system, you need to make sure your company’s ready.

Move to the cloud but keep your PBX

PBX stands for private branch exchange. It’s the typical company switchboard system that connects your internal phones to your external lines and allows internal calls within individual offices.
Many companies are ditching their PBX system to move to full internet-based VoIP when it’s time for an upgrade. But SIP (Session Initiation Protocol) is an alternative that gives you all cost and flexibility benefits of internet-based calls, but allows you to keep your current PBX system and traditional handsets.
Save with SIP

Save up to 90%

The savings you can make with a Planet Numbers VoIP system are staggering. Most users see a reduction in their monthly phone costs of at least 75%.

SIP Reliability

Customised to your company's needs

You can have as many phone numbers as you need and you can configure these in the way that matches your company’s structure. Because the system is cloud-based, you can change the configuration quickly and easily as your company grows and changes.

SIP to mobile

Integrate your mobiles

With a Planet Numbers SIP trunk you can integrate your team’s mobiles handsets into your office system.

SIP Numbers

Keep your existing phone numbers

Because our SIP systems are all about giving you exactly the set-up you need, you can choose brand-new phone numbers (including Planet Number’s range of easy-to-remember non-geographic ones like 0800s and 0300s) or simply use your existing numbers.

SIP Switchboard

Manage everything from your online dashboard

Want to switch on some of the system’s automated call handling services like call recording, voicemail or call queuing messages? Just log in to your online dashboard and you can do it in seconds. Need to redirect incoming calls from one of your lines to a mobile for a short period? No problem. Just log in to the dashboard dashboard and reconfigure your routing as often as you need to.

SIP Broadband

Get your broadband from Planet Numbers too

Naturally, our SIP Trunk systems work with any broadband internet provider. But if you’re having issues with your current ISP or simply want a quote for switching to Planet Numbers, just ask.
