Cisco HSI Release 4.3(2) introduces support for the following features:
H.323 Annex M.1 Support?Enables the interoperability of enhanced services with H.323 networks that support the H.323Annex M.1 protocol (for example, Cisco Call Manager). The tunneled QSIG content enabled by this feature supports interoperability not only with QSIG PBXs but also with SIP and other protocols (such as DPNSS and SS7), in conjunction with the Cisco PGW 2200. Enhanced service interoperability includes services such as call transfer/divert, call back services, and call completion. In addition, this feature enables full, end-to-end Route Optimization/Path Replacement for mixed Cisco Call Manager and DPNSS/QSIG PBX networks. Other services, such as message-waiting indication and caller ID services are also available.
H.323 Alternate Endpoint Routing Capability?Enables greater call-completion rates by allowing the HSI to attempt connection to multiple H.323 gateway destinations. An external route server can interface with H.323 gatekeepers by using the simple but powerful GKTMP interface, which provides a selection of destinations to which the HSI can attempt to connect.
Enhanced Performance?The Cisco HSI Release 4.3 provides improved performance. HSI 4.3 supports up to 10,000 simultaneous calls per HSI, at rates several times faster than previous releases.
Try CCM 4.3, it supports up to 10,000 simultaneous calls
