H.323 RAS Support in Cisco IOS Firewall
First Published: November 17, 2006
Last Updated: November 17, 2006
This feature introduces support for H.225 Registration, Admission, and Status (RAS) signaling in 
Cisco IOS firewalls. RAS is a signaling protocol that is used between endpoints (such as gateways) and 
gatekeepers. 
The H.225 standard is used by H.323 for call setup. H.255 includes RAS control, which is used to 
communicate with the gatekeeper. A RAS signaling channel enables connections between the gatekeeper 
and H.323 endpoints.
