Capabilities of Cisco 7200:
Support of QoS (Quality of Service)
Aggregation of customer broadband access - up to 16,000 PPP-sessions on the chassis
Fast routing Multiprotocol Label Switching (MPLS)
Support of IP Security (IPsec) VPN: up to 5,000 tunnels per chassis
Transparent signal forwarding H.323 and SIP
Integration of voice, video and data - voice port adapters, TDM support
Obviously SIP is considerably better than H.323 and complies with the understanding of IP-telephony as a global mass IP-service, and it should be implicitly considered right this way. And as SIP is able to serve not only telephony but also any communications at all in the real time over the IP-protocol; obviously it should become a base for other IP-services not yet existing but will appear in the future, as well.
