An NVM setting has been added that stores the state of Call Waiting Permanent Disabled so that the state survives a reset. This MIB enables the storage of the Call Waiting state in NVM. Some customers will want to leave this MIB at a default value of 0 because of the following scenario: 1. MSO issues a modem to end user A 2. A dials star code to disable call waiting 3. MSO reclaims modem 4. MSO issues the modem to end user B 5. B does not know why call waiting does not work. Values: 1 - Call Waiting Permanent Disable state is NOT stored in NVM, and Call Waiting returns to MSO defined default settings when a reset occurs. If neither sipCfgCallWaitingCapability nor sipCfgPortFeatureSettings is defined in the MTA configuration file, then Call Waiting will be enabled at reset. 2 - If the end user dials a dial code to disable call waiting, that setting will survive resets and will last until one of the following events occurs: end user dials a dial code to enable call waiting, or sipCfgResetCallWaitingStarCode MIB is used via SNMP. This MIB can only be set via the MTA configuration file.
