Internet Service Node (ISN) 2.0

Release Notes

Automated codec negotiation between ingress and egress gateway/endpoint during IP Transfer.

Metrics have been added to the Application Server to measure it’s internal response time and the ICM response time. Metrics have been added to the ISN Voice Browser to measure call arrival and transfer rates (cps). The transfer latency metrics in the ISN Voice Browser logs have been separated into the time to alerting and time to off-hook.

The RNA timer for transferred calls is user configurable at the ISN Voice Browser.

The Voice Browser and the Application Server may now be configured to not connect to SDDSN server.

The call will be restarted if certain egress endpoints fail. Specifically, when a transfer has succeeded, and the egress is a Voice Gateway that fails, the call will be restarted rather than disconnecting the caller.

The Voice Browser can now be configured to pass either the Dialed Number (DNIS) or Calling Line Identification (CLI) in the Calling Party Number parameter of the Setup message during IP Transfer.

Support for ringback and other tones (like tone on hold) have been added during Supplementary services (like Transfer, Hold, and Conference) invoked at Cisco CallManager.

1.2.Changes from Release 1.0.1

The default locale strings changed from en_US to en-us and from en_GB to en-gb to be compatible with current industry nomenclature. This affects the location for the media server system files used for built-in types such as numbers and currencies. The actual grammar definitions will work for both formats (en_US as well as en-us).

If upgrading from a system where the locale default is used, move the existing media server system files (e.g., 1.wav) from …/en_US/… directory to …/en- us… directory.

If the locale is not defaulted, there are three approaches:

Option 1: Change the scripts to use en-us rather than en_US and move the existing media server system files (e.g., 1.wav) from …/en_US/… directory to …/en-us… directory.

Option 2: Move the new prompt files (installed as part of the upgrade, e.g., USD_dollar.wav) from …/en-us/… directory to …/en_US… directory. This is the easiest approach, but will continue to be an issue with each release.
