How to choose
Which calling features should I compare?
Start with the features that affect daily call handling: auto attendant, call recording, number types, supported endpoints, included extensions and call queues.
Then compare the free plan and paid starting price. ChoiceCloud PBX lists plans from £4.99 per month, while some providers give pricing on request.
Which platforms does it need to run on?
Choose a service that supports the devices your staff already use. Board entries can run on the web, Android, iOS, Windows or macOS, with support varying by product.
An API mark matters when another software system needs a public connection to the phone service.
Can I try a cloud PBX before paying?
Check the free-plan and free-trial marks separately: a free plan can continue without payment, while a trial is a limited test period.
GoTo Connect lists no free plan and pricing on request. ChoiceCloud PBX also lists no free plan, with paid plans from £4.99 per month.
Does it need an API or open-source code?
Use the API mark when you need a public way to connect the phone system with other software. Check the open-source mark if access to the underlying code or its licence matters to your organisation.
If neither is required, focus on the supported endpoints, extensions and call-handling features instead.
