This combination of voice solutions leverages Cisco's proven track record of being able to effectively handle time-sensitive traffic, such as Systems Network Architecture (SNA) over IP networks. Cisco IOS software also incorporates built-in quality-of-service (QoS) features along with standards-based (FRF.11 and FRF.12) encapsulation and fragmentation providing efficient direct transport of both voice and fax over IP, Frame Relay and ATM networks. These IOS solutions enable time-sensitive voice traffic to be moved across even low-bandwidth WAN connections with the priority and quality voice/fax demands...
