Feature server

Last Updated : Jan 23, 2024 |

A feature server provides Communication Manager features to the SIP endpoints registered with Session Manager. The feature server uses the half-call model of IP Multimedia Subsystem (IMS).

The feature server supports full application sequencing.

The feature server has the following limitations:

  • The feature server does not support routing of PSTN calls directly to ISDN trunks for IMS users. You must administer the dial plan to route all PSTN calls to Session Manager over the IMS trunk group.

  • The feature server does not support traditional endpoints, such as DCP, H.323, ISDN, and analog.

  • The feature server does not support call reconstruction.
