Adepteo are a key Grandstream reseller in the UK and work closely with their distributor.
Our systems and services are closely coupled tied to the Grandstream product range and we pride ourselves on providing a very easy implementation of Grandstream phones into our service. When a phone is shipped it is automatically set up to configure to our system if required. A simple power on sequence in your office and the phone should become part of your Adepteo phone service.
If you use the services of another provider then these Grandstream phones work with all SIP compliant systems that you are likely to come across.
