A call flow is a simple way to create “journeys” for your call to go on.

For example, when a call comes in, you can choose whether to send it to a user, play a sound, or send it straight to voicemail.

You can view:

Book A SIP Trunking Consultation Call

Switching your telephony to IP-based is something you need to do sooner rather than later if you wish to avoid disruption to your business.

We have aimed to provide all the information required to make an informed decision about switching to IP, but sometimes, it’s nice to get some reassurance.

Book in a consultation call and we will answer all your questions about our SIP trunking solution and how to switch with as little disruption as possible.

If you are already using a SIP trunk provider and wish to switch to Ballscoigne, we can talk you through that process.


Our SIP trunking product lets you take control of your telecoms.

Fast Fixes

Our VoIP platform is built off a robust system capable of handling many connections simultaneously – all this means we can diagnose and fix faults remotely without needing to send an engineer out.


“My company relies on making calls, so I needed a cost-effective, reliable SIP trunking product. I went with Ballscoigne because they had good call rates and, while I’ll probably never make use of them, the backup features will be great in a catastrophe.”
