Product Description
Designed for MSOs offering SIP trunking, hosted voice, and high-speed data services, InnoMedia's ESBC 8528-4B is a highly integrated and highly manageable Enterprise Session Border Controller (ESBC) that can be auto-provisioned and remotely managed. With InnoMediau2019s exclusive Smart-DQoSu2122 technology enabling device-initiated DQoS UGS service flow establishment, ESBC 8528-4B is ideally suitable for MSOs offering bundled services with end-to-end quality of service over HFC cable plants. The built-in B2BUA and SIP ALG capabilities enable wide deployment by MSOs addressing SIP-PBX interoperability for SIP Trunking as well as providing simple NAT Traversal for Hosted PBX Services.
Product Feature
The SIP trunk path provides SIP normalization, NAT traversal, topology hiding, and security for MSOs offering SIP trunking service to enterprise customers with diverse IPPBX and network configurations. It includes B2BUA for SIP normalization, a Registrar for User Agent (UA) registration, TLS block for secured signaling, and NAT traversal for proper SDP address correction. The UA (e.g., IPPBX) registers to and communicates with the ESBC which terminates UA traffic and re-initiates normalized SIP packets to communicate with the MSOsu2019 network servers. Together with Smart-DQoSu2122, the MSO is able to offer QoS ensured SIP trunking service.
