Feature Access Codes (FAC)

Feature Access Codes, whether dialed or administered buttons, do not work.

Non-IP trunks/stations, including such circuit-switched TDM resources as DCP, analog, or ISDN-PRI.

These resources are unavailable until the H.248 link is re-established.

Terminals

Time-of-Day, busy lamp states, and call appearance status on some phones might not instantaneously reflect the correct information until the H.248 link is re-established.

Adjunct Switch Application Interface (ASAI)

ASAI-based applications that use timing loops, time-related methods, or events might not perform as intended. In addition, applications that do not accommodate time-outs or missing state transitions might behave unpredictably.

Voice mail adjuncts (Communication Manager Messaging application)

During Link Recovery, callers connected to the Communication Manager Messaging application remain connected even if they stop responding. Such calls might be automatically disconnected by the Communication Manager Messaging application if the connection remains intact without the calling party entering tone commands to the Communication Manager Messaging application or voicing a message.

Call Detail Recording (CDR)

Call records cannot reflect the correct disconnect time if the calling party hangs up before the link recovers.

Call Management System (CMS)

Measurements collected during the recovery period might be inaccurate in those reports that rely upon time-related data.

Property Management System (PMS)

Automatic Wake-up, Daily Wake-up, and Housekeeping Status features might not operate as expected if the link fails and the time to search for alternate resources exceeds the PMS application’s time-out parameters.

For example, if a guest has a wake-up call schedule for 6:15 AM and the H.248 link goes down at 6:10 but recovers at 6:20, then the guest receives no wake up call at 6:15.

Conversant voice response systems

Conversant applications that use timing loops, time-related methods, or events might not perform as intended. In addition, applications that do not accommodate time-outs or missing state transition(s) might behave unpredictably.
