Call tagging associates a text string with a call. That string remains with the call during transfers and forwards. That includes calls across a multi-site network.
On Avaya display phones, the text is shown whilst a call is alerting and is then replace by the calling name and number when the call is connected. On analog phones with a caller ID display, the tag text replace the normal caller information.
Applications such as SoftConsole display any call tag associated with a call. If the call is parked, the tag is shown on the call park slot button used. A call tag can be added when making a call using SoftConsole or one-X Portal. A tag can be added to a call by an Incoming Call Route or by an Voicemail Pro Assisted Transfer action.
