Marketing and billing features:

• Integrated pre-paid, post-paid, and external application billing of calls in and out, numbers, telephone accounts, etc.
• Unlimited levels of reseller. Resellers can set their own prices for outbound calls, numbers, telephone accounts, etc. Each reseller can define as many rate plans as they wish, and assign different customers different plans. The system owner creates groups of destination patterns, eg. 0044 for the UK, and resellers set how much markup they wish to charge their customers. Customers, including resellers, cannot see which other customers are on the system, or even whether their parent reseller is the system owner or not, making the system truly multi-tenant.
• Connection to unlimited PSTN carriers with different carriers to different destinations. Each carrier can have prices set for each destination, and automatic least cost routing (LCR) can choose the cheapest carrier for each destination. Prices can be imported and exported from/to a spreadsheet.
• Production of PDF invoices for each customer. Invoices can be emailed automatically to customers, or to resellers for forwarding. Invoices can be reviewed and approved within the web interface before being sent. Customers and resellers can search and download all past invoices on the web interface, and resellers can manage which invoices are paid, due, or overdue. Customers can choose which currency their invoices appear in.
• Customers can be given the full PBX interface or a simplified multi-line residential interface.
• The system owner and resellers can administer prices, numbers, resellers, etc, on the web. Web supports SSL (requires third party certificate). The web interface can be re-branded to your own design.
• The system owner and resellers can set the price of features such as telephones, hunt groups, queues, IVR menus, conferences, etc. The maximum number of each feature per customer can set, and a number of each feature can be included free. For example, a customer could be given 5 free telephone accounts, then charged 9.95 per month for any extra up to a maximum of 20, when they may add no more. Prices can be monthly, 3 months, 6 months, or annual.
• Customers can be limited to a certain number of concurrent calls inbound and outbound. This can be set for each individual customer.
• Rate plans can optionally include a number of minutes per month. Once used up, call prices revert to normal. Minutes call option roll over for one month. Which destinations use the included minutes can be configured on the web interface, and different rate plans can use different sets of destinations.
• The system owner and resellers can create products for customers to purchase. Products can be physical (such as SIP phones), services, or blocks of minutes. Billing and invoicing for products is integrated into customers' accounts. Recurring billing is supported.
• Other charges can be attached to customers' accounts for extras such as telephones, DSL circuits, etc. Charges can be one-off, monthly, quarterly, or annual. Charges are integrated into billing and invoicing.
• Affiliates can be created, where the system owner and resellers can give a percentage of revenue from one customer (including resellers) to another customer.
• Customers may choose their telephone numbers from a list, and forward them to telephones, external numbers, hunt groups, IVRs, etc. Different numbers can be priced at different rates, both by area code and by number elegance (e.g. 1-800-555-5555 is more expensive than 1-888-713-2894).
• Both inbound and outbound calls can be charged at different rates at different times of the day and different days of the week.
• Self service sign-up using a wizard. Resellers can set which rate plans customers may choose from on sign-up.
• Calling cards. Resellers can set their own prices and choose features available to users. Users are cut off when credit runs out, and resellers can set whether a warning is played to the user, called party, or both. Users can make multiple outbound calls from one inbound call. Systems with hundreds of thousands of cards are currently in use.
• Call shops, where a customer can walk in, pay, and make calls from one of the shop's telephones.
• PayPal and direct debit integration for customers to top up their accounts. Credit card integration is available at extra cost.
• Sales tax, VAT, etc, can be automatically calculated and added to invoices, transactions, and CDRs. Customers can be marked as either liable for tax or not.
• The system owner and resellers can produce pre-paid vouchers to sell through retail channels. Customers can redeem these vouchers automatically on the web interface or via telephone.
• The system owner can create an unlimited call IVR which allows callers to call in without authentication. They are then allowed to call any destination which costs the system owner less than the revenue they receive for the incoming call. The system owner can set allowed destinations via a minimum profit margin and percentage, maximum outbound call costs, and fine tune using a class of service.
• Wholesale customers can be created and administered purely from the web, with authentication via SIP username and passwords, source IP addresses, or called number prefixes.

Customer features:

All of the following work seamlessly with multiple levels of customers and resellers. Customers can define their own settings if you choose to allow them to, and they and any resellers are billed automatically.

• Per customer centrex numbers forwarded to sip phones, voicemail, etc. Each customer can define their own feature codes, and multiple customers can define the same code with different destinations. Customers can change feature codes for voicemail, etc, as they wish. This reduces training costs when switching from a legacy PBX.
• Calls can be authenticated by username and password, callerid, account and PIN entered in an IVR, or called number prefix. This allows billing of calls from customers with Cisco VoIP routers.
• Telephone features include telemarketer block, callerid block, selectable callerid for both internal and external calls, call forwarding, variable ring time, do not disturb, call park, etc.
• Voicemail with external access, email notification, web access to messages, and multiple greetings (unavailable, busy, and temporary). Greetings can be uploaded and downloaded on the web interface. Notification of voicemails can be via MWI, email, SMS, and outbound calling, and work with messages left via telephone, web, or SOAP API. Dial out and call back to the sender are supported from the voicemail menu, and fully integrated with billing.
• Multi-level IVRs and auto attendants. Every key on the telephone keypad, as well as time out, can be assigned to any feature on the system, or to an external number. External calls are billed to the IVR owner. The messages played to callers can be recorded from a telephone or uploaded in a .wav file.
• Queues / ACD. Unlike Asterisk's queues, calls can be queued across multiple machines, with the machines voting on which call gets forwarded to an agent next. Should one machine crash, calls on other machines are moved up the queue. Destinations can be telephones, external numbers, and SIP URIs. Queues can be assigned priorities, with calls on high priority queues delivered first. Reports can be generated per queue and per agent.
• Conferencing. Customers can set when the conferences run, how many people may join, different PINs for administrators, talkers, and listeners, and a set of telephone numbers and email addresses to notify when conferences start. Conferences can be recurring on a daily, weekly, or monthly basis. Numbers can route straight into a individual conference, either with or without a PIN.
• Fax to email and fax to mailbox with notification via email and SMS.
• Parallel, serial, and circular hunt groups. Hunt groups can call telephones, external numbers, and SIP URIs.
• Group and number pickup.
• Per telephone and shared speed dials.
• User settings can be bulk imported from a .csv file.
• Virtual telephones, where a telephone account can be logged in on top of a physical telephone and change its settings. Virtual telephones can move between physical telephones for a "hot desk" environment. This is sometimes known as "virtual extensions" or "extension mobility".
• Calls can be routed by date and time of day. Dates and times can be specified up to 20 years in advance, and can be any combination of times, days of the week, days of the month, months, and years. For example, between 8:00 and 10:30 on the first Monday in Januaries and Februaries between 2010 and 2015. Routing can be changed instantly via web or telephone.
• Routing of calls by callerid, by exact number, area code, country, etc. For example, all calls from a region can be routed to the branch in that region.
• Unlimited classes of service on outbound calls. Classes can be defined down to an individual number.
• Call recording, with comprehensive search and listen on the web. Customers can be billed for both recording and storage.
• Call back to authenticated callerids.
• Call screening, where called parties are asked if they wish to accept calls. This is integrated with billing, so answered call legs are billed even if the call is rejected.
• Paging, with auto-answer on compatible SIP telephones.
• Dial by name, integrated with the main user database and voicemail recorded names.
• Busy lamps. Unlike Asterisk, these work in a cluster where more than one machine is delivering calls.
• Customers and resellers can view invoices, transactions, and CDRs (history of calls made) on the web, and download transactions and CDRs to a spreadsheet. CDRs include real time call costs.
• Customers are automatically notified when their balance drops below a set amount, and they can have the system automatically request a top-up when this happens.
• Each customer can be in a different time zone, set on the web interface. All dates and times the customer sees on the web and invoices are in their local time zone.
• If the system owner allows, customers can port in numbers from other providers and configure them on the web interface themselves.
• Click to dial on the web interface and SOAP API. This can be used for both outgoing and incoming calls. Incoming calls can be routed to any feature of the system such as telephones, queues, hunt groups, etc, making creation of "Click here to call us" links on customers' own websites easy. The customer is billed for any chargeable calls.
