The device now supports configuration of the T310 timer for the ISDN variant National ISDN with sub variant 2 (NI2). This solution is similar to the T310 timer for DMS and Euro ISDN. The T310 timer is the timer that is set when the ISDN interface receives a Call Proceeding message. If no Alerting, Progress, or Connect message is received within the duration of T310, the call clears.

The T310 timer can be configured using the existing parameter, ISDNTimerT310. When set to 0, the timer uses the default timer according to the protocol’s specifications.

The device now supports a bit-field that determines the behavior of the Q.931 protocol. This is configured per trunk, using the new parameter, ISDNNSBehaviour2. The relevant bit is NS_BEHAVIOUR2_ANY_UUI (0x0008). When this bit is set, any User to User Information Element (UUIE) is accepted for any protocol discriminator. This feature is useful for interoperability with non-standard switches.
