Each client (or separate office, tenant) has a dedicated, isolated cloud PBX , with separate :

• exntensions (with PBX functions — followme, Forward, Voice/Video Mail, Blacklists etc..)
• VoiceMail boxes,
• Call parkign spaces, Park&Announce
• Auto-attendants/Virtual Offices,
• Page/Ring Groups,
• Queues,
• multiple Music-on-Hold classes on separate storage,
• Conferences
• Inbound/Outbound routing logic
• Email SMTP account to delivery Reports/Notifications/Alerts

All clients/offices share the same server and the same asterisk instance and managemed in one place. With a multitenant architecture, a software application is designed to virtually partition its data and configuration, and each client works with a customized virtual application instance. Using the same asterisk instance for all the clients is a real cost and resource saving solution. Some more key features:

• supports custom scripting, i.e. assigning a dialplan contexts to Feture codes, which connects extensions with unlimited functionality of the asterisk dialplan.
• Call recording (full or by one-touch on demand recording while conversation).

Uppong receiving call, manager can activate inbound route with actions:
