What You'll Need To Get Your PBX Working with our SIP Trunks

You already have a SIP, VoIP compatible PBX onsite or in the cloud.

Nearly all onsite SIP-compatible PBXs will work with our trunks and channels, we haven't found one that doesn't yet

Some cloud PBXs are not compatible as they want to force you to use their own trunks and channels or are based on ancient technology.

You can carry on maintaining your PBX as you do now with the benefit of lower bills for calls.

If you are an MSP and manage several PBXs on behalf of your customers, let’s get together and see how we benefit both you and your clients in terms of costs and reliability.

We have helpful technical staff who can quickly help you with anything from porting requests to fault finding on your configuration.

 

What to Look for when selecting SIP Trunk Providers

Just like any technology you need you to need your SIP Trunk Providers to be able to offer the right level of technical support.

The closer they are in size to your business the better understanding they will have of how to serve you. If they are too big you won’t get the service, you need if they are too small you won’t benefit from their scale and expertise.

You need to decide whether you can work together with your prospective new SIP Trunk provider.
