Traditional Phone Service(TPS): Desk phone with traditional voicemail

TPS w/IRIS Unified Messaging: Desk phone with voicemail to email inbox

Enterprise Voice w/IRIS Unified Messaging: Soft phone via computer interface, with voicemail to email inbox

Hunt Group - Incoming calls are rotated through a pool of lines until a free line is found and the caller is connected

Call park - Allows a call to be parked at a specific parking number for retrieval from any extension. Allows a person to put a call on hold at one telephone and continue the conversation from any other telephone

Conference call - TPS allows up to 6 parties to be connected; EV allows up to 35 parties to be connected

Call forward - allows you to forward incoming calls to a different telephone number

Divert calls to voicemail - Call forward your calls directly to voice mail

Team line - An additional line on the phone that may ring on several phones at the same time

Automatic call distribution (ACD) - This is a special line that departments use for a call center. Incoming calls are distributed to a specific group of agent telephones. If the number of active calls is less than the number of agent telephones, the next call will be routed to the agent telephone that has been in the idle state the longest. If all agent telephones are busy, the incoming calls are held in a first-in-first-out queue until an agent telephone becomes available

Response group services - Incoming phone calls are routed or queued to one or more designated agents

Call pick-up/Delegate - Allows you to pick up another ringing line from your phone

*Message Waiting Indicator - Indicates that you have a voicemail that has not been listened to. On the TPS with a desk phone, the indicator is a red flashing light; on IRIS UM, the indicator is a flashing telephone icon in the system tray.

**Transfer voicemail to other system - There is no way to transfer voicemail from one system to the other. You may forward IRIS UM voicemails to other people via email, or you may download and forward a traditional email via the web interface.
