PBX in a flash based Asterisk Server based on a HP Proliant N36L server. PBX in a flash pre-installed and configured with a FREE outgoing SIP trunk from Gradwell. Can be installed at your premises at additional cost. You will need a static IP address to set this up. I suggest creating a subdomain like sip.mydomain.com that is directed to your static IP address for easy configuration. 
Only £529 with FREE trunk
If you are interested in this or need any other assistance then please call or fill in THIS FORM and you will be contacted soon. The FREE outgoing SIP trunk will be supplied once a direct debit or credit card mandate has been set-up for outgoing calls, and £10 call credit is taken. Call charges can be found here. We can set-up an outgoing CLI for your outbound calls for a small one off charge once we have received proof you own the number. We can supply VOIP phones configured for use with the server if needed.
