Extension to Cellular upgrades from prior versions

Last Updated : Aug 09, 2021 |

Extension to Cellular is available only with Communication Manager Release 1.3 or later. The Extension to Cellular releases can be administered and operated concurrently on the same Avaya server running Communication Manager. You can continue to support users with Extension to Cellular releases 1 through 4.1. Or you can upgrade all users to the latest version of Communication Manager.

Note:

Endpoints configured as XMOBILE cannot access important enhancements to EC500, such as support for SIP trunk groups. You must follow the steps in this section to gain access to these enhancements for your EC500 users.

If you are converting from Extension to Cellular versions 1-4 you must perform the following steps to update to the latest version as part of Communication Manager Release 5.2 or later:

  1. Enter change station n, where n is the station you want to change.

  2. Set the XMOBILE Mapping Mode to none.

    All previous mapping of XMOBILE stations, the way Extension to Cellular used to be administered, cannot interfere with Extension to Cellular.

  3. Set up the new office telephone to cell phone mapping in Mapping an office telephone to a cell phone.

  4. Test the system.

  5. If the system works, remove the XMOBILE station records.

    This last step frees up stations that go toward the maximum number of stations allowed.

Starting with Extension to Cellular 5.0 (Communication Manager Release 2.0) introduced support for the Off-PBX Telephone Integration and Mobility (OPTIM). Once XMOBILE Mappings are converted to OPTIM, further upgrades from that release to higher releases are automatic. Only new capabilities need to be administered when upgrading to new releases. Some of those include:

  • Support of up to 4 OPTIM applications per station extension – up to 4 phone number mappings can be administered per station extension.

  • Self Administration Feature (SAFE) Access Codes so users can enter and change their own cell phone numbers. For more information, see Creating a Self Administration Feature (SAFE) access code. Using this feature, you can have up to 4 SAFE Access Codes per extension to modify up to four phone numbers per extension.

  • Administration of the barge-in tone for added security. For more information, see Administering the barge-in tone.

  • Mapping dialed extensions to the new Feature Name Extensions. For more information, see Setting up Feature Name Extensions (FNE)s.

  • Support of multiple sets of Feature Name Extensions.

  • Fixed Mobile Convergence (FMC) applications support PBFMC and SPFMC. PVFMC applications support dual-mode cellular phones.
