Description of PBX features:

Auto Attendant (AA)
An Auto Attendant system allows callers to be automatically transferred to a user's extension without the intervention of a receptionist.
Automatic Call Distributor (ACD)
An ACD system distributes incoming calls to a specific group of users/agents.
Automated Directory Assistance (ADA)
An ADA system allows callers to route calls to given employees by keying the letters of the employee's name.
Automatic Ring Back (ARB)
An ARB system provides callers with an option to be called when the destination they failed to reach becomes available.
Call Accounting
A Call Accounting system collects data when a call is made and attaches a cost and a location to the call. Our platform generates accounting CDR records. It also maintains the incoming and outgoing call logs in the user's Account File Storage.
Call Forwarding
A Call Forwarding system allows an incoming call to a called party, which would be otherwise unavailable, to be redirected to some other telephone number where the desired called party is situated. This feature provide a very powerful and flexible call control environment. It can be used to implement many different types of call forwarding.
Call Park
The Call Park feature allows a person to put a call on hold at one telephone set and continue the conversation using some other telephone set. The feature implements a multi-line, queue-type Parking Service for each User Account. Additionally, for individual companies, groups or hosted domains, the Park Center feature allows Domain users to park a call in a Domain-wide Park Center, where it can be picked up by any other user of that Domain.
Call Pick-up
The Call Pick-up feature allows a person to answer someone else's call.
Call Through
A Call Through feature allows a user to call the PBX system first, and then make the system place a (usually expensive) call on the user's behalf. 
Call Transfer
A Call Transfer is a mechanism enabling a user to relocate an existing call to another device or extension. Our IP PBX platform fully supports SIP operations required to implement Call Transfer. The XIMSS module allows XIMSS-based clients to implement all types of Call Transfer operations. The real-time application environment can automatically accept Call Transfer operations allowing calls established with applications (such as IVR) to be transferred without limitations. Real-time applications can also initiate all types of Call Transfer operations. Our PSTN gateway implements Call Transfer internally, thus providing unlimited call transfer functionality for PSTN calls.
Call Waiting
The Call Waiting feature allows a calling party to place a call to a called party which is otherwise engaged, so the called party is able to suspend the current telephone call and switch to the new incoming call, and then back to the previous call. Our own Pronto! XIMSS based client can handle several calls at once, so it doesn't really need the Call Waiting feature or implement it locally. A special real-time application can be used to emulate the legacy call waiting feature for users with single-line devices.
Call Return / Camping
The Call Return feature allows a called party to place a call back to the calling party of the last received call.
Conference Call
The Conference call is a call with more than two participants. This feature is built into our own Pronto! XIMSS based telephony client.
Custom Greetings
The Custom Greeting feature allows users to change their announcements according to special criteria. The VoiceMail application can play Custom Greetings and they can be edited by usign the Services application. The Custom Greetings (wav files) can also be uploaded directly to the Account File Storage.
Direct Inward Dialing (DID)
The Direct Inward Dialing feature (offered by phone companies) allows our IP PBX to receive calls for a range of numbers, to get the information about the number dialed, and to route the call to proper extension based on that information. If the phone company provider has enabled the DID service for your company or group, our PBX will receive the DID information to be able to send the external call to any local or remote Account or Group.
Direct Inward System Access (DISA)
The Direct Inward System Access feature allows a calling party to access internal features from an outside telephone line.
Extension Dialing
The Extension Dialing feature allows the system users to call each other using short (2-5 digits) numbers. The User Accounts can have short numeric Aliases, implementing independent Extension Dialing plans within each company, group or domain.
Follow-me / Find-me
The Follow-me feature routes incoming calls to a person trying each number in a pre-configured list until the call is answered. This feature implements very flexible Follow-me configurations. Unlike many other PBX systems, our PBX can "fork" calls, adding new numbers/addresses to the set of devices being alerted, with the option that all devices in the set ringing simultaneously.
Message Waiting Indicator (MWI)
The Message Waiting Indicator is an audio or visual signal the telephone device send to inform that a voicemail message is waiting. This feature can be used with any SIP-based device to implement Message Waiting Indicator.
Music on Hold (MOH)
The Music on Hold feature allows the system to play pre-recorded music to fill the silence that would be heard by telephone callers that have been placed on hold. The Pro Park Center and many other modules use the system's ability to play any pre-recorded media file to implement Music on Hold feature.
Night Service
The Night Service feature allows the system to route incoming calls depending on the current time of day. The Call Control features and Signal Rules implement very flexible Night Service configurations: the calls can be processed depending on the time of day, the working hours of the callee, the callee presences, etc.
Vertical Service Codes (VSC)
The Vertical Service Codes are special short telephone numbers starting with the star (*) symbol/key, used to access system services. Our platform  implements various Service Codes.
Voicemail (voice mail, vmail, or VMS)
Voicemail is a system allowing callers to record and store phone messages, and allowing its users to play and distribute stored messages. The VoiceMail feature allows caller to store messages. Voice messages are delivered to the callee INBOX as any other E-mail message, and can be filtered, sorted, and processed using the Queue Rules. The built-in Services module can be used to retrieve and manage recorded messages. At the same time, any POP, IMAP, MAPI, XIMSS client or Pronto! Web Interface can be used to retrieve and manage recorded messages.
