Extension Mobility

Extension Mobility

Extension mobility allows you to use your IP phone's extension number and password to log in to any other IP phone of the eSpace 7900 series. Your configurations (such as the call history, contacts, line button and programmable button settings) and services to which you have subscribed will be automatically downloaded to the IP phone you newly log in.

  • Before using the extension mobility function, ensure that the extension mobility service rights have been configured on the server for the IP phones in both the home area and visited area. For any questions, contact your system administrator.
  • For the eSpace 7900 series IP phones, if the IP phone that you log in to is different from the original IP phone model, only the functions of the phone that you have logged in to are effective.
  • In extension mobility, only the primary account (first account) of the original IP phone can be used to log in to another IP phone in the UC2.X or IMS+UC network environment, and only the uPortal account can be used to log in to another IP phone in the EC6.X network environment. Extension mobility is available only within the enterprise network.
  • Extension mobility is not supported between the eSpace 8950 IP phone and eSpace 7900 series IP phones.

Using Extension Mobility

  1. Log in to the IP phone.

    • In the UC2.X network environment, enter your primary number and password, and press Log In.
    • In the EC6.X or IMS+UC network environment, enter the account and password, press Log In.

      If the IP phone you want to log in has any registered account, log out of the account first.

  2. Deregister the login account when extension mobility is no longer used.

    In the EC6.X network environment, the IP phone automatically logs in using the original default account after the account used for extension mobility is deregistered.

    In the IMS+UC network environment, if the current login account is a roaming account (which is an account logged in to another phone for extension mobility), the phone automatically logs out of this account and returns to the login screen when a specific period (configured by your system administrator) expires. If the phone has registered an account before the roaming account is logged in, the phone is automatically logged in using the registered account after the roaming account is logged out.
