The introduction of VoIP into legacy telecommunication architectures based on the Public Switched Telephone Network (PSTN) is creating a wide range of problems that both Service Operators and Carriers must address. The TCP/IP protocol, and packet switched networks in general, have been historically designed to carry packet-based data very accurately, but with very little attention given to packet delay. Unfortunately, voice and real-time multimedia traffic is highly delay-sensitive, and as many operators are learning, it is very difficult to maintain "legacy voice" QoS with VoIP.

The IP Multimedia Subsystem (IMS) is a standardized next-generation networking architecture that provides mobile and fixed multimedia services. IMS allows operators to introduce enhanced IP-based multimedia services such as presence, push-to-talk and combined circuit/packet services. Accanto solutions allow rapid provisioning and in-depth monitoring and troubleshooting of these advanced services.

Accanto ‘s VoIP solutions give operators accurate insights into their end-to-end VoIP service architecture. From the Signaling Link Status Monitor, to rapid call transaction drill-down capabilities, Accanto is one of the industry’s proven leaders in VoIP service monitoring and analysis.

The adoption of packet-switched technology for the core allows operators to focus on a single network instead of different networks for voice and data services. In this migration, the operator must ensure that the new architecture provides the same QoS that customers have come to appreciate with traditional circuit-switched networks. To ensure the highest possible voice quality in an IP-based network, Accanto provides a complete toolset for intrusive and non-intrusive troubleshooting and monitoring.
