The Cisco AS5350XM Universal Gateway can meet service provider and
enterprise session-border-controller (SBC) requirements through
support for the Cisco Multiservice IP-to-IP Gateway, an integrated
Cisco IOS® Software application that facilitates connectivity between
independent VoIP and video networks.
You need an IOS release with Multiservice support (now called Cisco Unified Border Element, formally Multiservice IP-to-IP Gateway).
You can click on Search By Feature, and put in Multiservice. It looks like you need at least IP+ or Enterprise and 12.4 to get that feature on the AS5350XM.
