Keywords:
Device Adapter supports Virtual Office (VO) only for UNIStim endpoints with the following terminologies:
  • Home set: The home set is the default set that is programmed with the user identity. However, logging in by MDA and Sequential Registration might change the home user identity.
  • Guest set: The guest set is used to log in using the home user identity.
  • Home button: The home button is a soft key used to regain the programmed identity of the set.
  • Virtual button: The virtual button is used to change the current station identity to another.
With the Virtual Office (VO) feature functionality on CS 1000, you can log in to the phone that is configured to support VO on a different Communication Server (CS) on the network by using a user ID and password. The user ID can be one of the following:
  • A local DN for Terminal Number (TN) on the same CS.
  • A complex number, if TN exists on another CS.
  • Coordinated Dial Plan (CDP) number: CDP is a private network dial plan that is used within a local cluster of CS 1000 servers.
  • Uniform Dial Plan (UDP) number: UDP is a private network enterprise canonical dial plan that expands the CDP local network to a global network with multiple local networks. A global network can make calls between local networks using the private dial plan.
  • Transferable DN (AC + HLOC + DN): UDP number with the network prefix added to it. Network prefix is the numbering plan access code.
When you log in to the virtual office at a guest station, the endpoint takes over the identity of the home station, which means that the endpoint logs out from the local station. When you log out from the guest station, the endpoint reverts to its original identity.
Note:
  • Terminal Number (TN) is a unique hardware ID for a phone that is registered with Device Adapter, which means that there is a unique TN available per ADA node.
  • Virtual Office also supports Emergency Dialing.

Virtual Office functionality for UNIStim phones on Device Adapter

Device Adapter provides the following functionality of Virtual Office feature for UNIStim phones:
  • Supports station configuration by allowing you to log in by using VO credentials at the guest station. When you log in at the guest station by using a virtual key, the station using the user identity at that time (that is either home station or another VO guest station) logs out. You must press the Home key to log into the home station again. Pressing the Home key logs you out of the current guest station.
  • Uses SIP handle plus SIP domain as user ID.
  • Supports home station configuration by allowing you to log in by using VO credentials at the home station.
  • Supports normal functionality of a station when you log in by using VO credentials and a normal user presses the Home key.
  • Supports login using alphanumeric characters.

Loadware upgrade

Unistim phones does not upgrade from loadware in the VO logged-out state.

Virtual Office, Sequential Registration, and Multi-device access features comparison

In MDA and Sequential Registration features, change of registered user requires a TN change. For example, you are logged into a set as TN xxx xx xx xx. Another user does an MDA or Sequential Registration login on the same set as TN yyy yy yy yy. If you log out and try to register again on the same set, then the set will not return to its original identity, that is TN xxx xx xx xx. But, the set will register as the changed TN yyy yy yy yy.
In case of Virtual Office, you can program certain user devices to act as a home device. This device corresponds to the device on which the user initially logged in to, assuming the user carries out Sequential Registration. The VO feature works as follows:
  • The VO user initially uses the home device as per Sequential Registration.
  • The user logs in at a guest device using the login identity and not the TN, which is used for Sequential Registration. The guest device takes the home device identity.
  • The original device is VO logged out. To return to the original home device identity, user presses the Home soft key.
  • If user exits the home device or performs some action to return to the home device or does VO login on any other device, the guest device will regain its original identity.
The following are the limitations of Virtual Office in Device Adapter:
  • If during the registration process the home station and guest station have different TN (hardware port ID) but same hardware device ID, then registration fails.
  • If during the registration process the home station and guest station have the same TN but different hardware ID, then VO works as Sequential Registration.
  • If the request comes from the same Avaya Breeze® platform, then the oldest registration gets unregistered by the cluster and the latest one gets registered.
  • If the request comes from different Avaya Breeze® platform nodes, then the setting for Max Simultaneous User and the Block new registrations on the Session Manager determines the configuration.
Use the ProVision tool to migrate Virtual Office Login Allowed (VOLA) and Virtual Office User Allowed (VOUA) CoS values of TN block of CS1k–IP endpoint to the feature mnemonics of Communication Manager endpoint.
You cannot use ProVision tool to migrate the VOLO attributes, TN range for emergency calls from Logged out sets and SIP domain for emergency calls from Logged out sets. You must configure them manually.
