Feature Mode for SCCP FXS Ports in Cisco IOS


First Published: June 22, 2006
Last Updated: August 1, 2008

Feature Mode for SCCP FXS Ports in Cisco IOS provides enhanced call-control mode capability on analog ports on Cisco IOS voice gateways. When feature mode is enabled on a Cisco IOS voice gateway, calls through the analog FXS ports are controlled by Cisco Unified Communications Manager or by Cisco Unified CME, with basic call support in SRST mode. The SCCP telephony control (STC) application on the Cisco IOS voice gateway functions as a proxy to translate call-control messages between the Cisco call-control system and the voice gateway.
