Telephone type XMOBILE is not listed in the table. Endpoints configured as XMOBILE cannot access important enhancements to EC500, such as support for SIP trunk groups. For information about converting from an XMOBILE configuration to the officially supported EC500 configuration, see the Extension to Cellular upgrades from prior versions section later in this chapter.

Prior to Communication Manager Release 10.2, J139, J159, and J189 must be aliased. The J139 IP Phone should be administered as J169 IP Phone. The J159 IP Phone should be administered as a J169 IP Phone with single expansion module, and the J189 IP Phone should be administered as a J179 IP Phone with at least one expansion module. If a JEM is attached, J189 IP Phone will be administered as a J179 IP Phone with two or more expansion modules. With Communication Manager Release 10.2, the J139, J159, J189, and J189CC endpoints will appear as AvyaSIP or AvyaSIPCC type set. You must administer these endpoints in System Manager. When you add these endpoints from System Manager, Communication Manager only display these endpoints.
