VoIP stack is always in synch with the wireless transport - as the DRAP is
integrated into the VoIP stack all calls are terminated according to the VoIP
standard. Even if no resources are available, the voice gateway receives an
appropriate message from the WiLink-I system and sends the required
signaling message according to the VoIP standard used.
4.10.1.3
Supporting Generic (3rd Party) VoIP Services
When using VoIP devices that do not support the DRAP protocol, the required
service can be provided through a Data (L2) service with a CG QoS (see
Section 4.10.4.7
) that is defined in accordance with the estimated bandwidth
required for the service. The required bandwidth depends on several parameters,
such as codec type, sample rate and T.38 Fax Relay support. The service
parameters depend also on the marking features of the VoIP equipment (the
ability to use either DSCP or 802.1p to distinguish between RTP, RTCP and VoIP
Signaling, and Data traffic).
The system includes several pre-configured Service Profiles for commonly used
VoIP applications. For details on the pre-configured profiles, refer to
Section 4.10.6
. For details on defining Service Profiles for generic VoIP devices,
refer to
Appendix B
.
4.10.1.4
Advanced and Quick Service Modes
A WiLink-I Base Station can operate in either Advanced or Quick Mode of service
provisioning.
Advanced Mode enables operators to completely deny services to SUs that are not
defined in the system. This increases the security of the system but complicates
slightly the installation process as an SU must be defined in the system before it
can be registered and receive any service.
Quick Mode is intended primarily for scenarios where the operator is not
concerned with potentially "stolen" SUs, and wishes to provide basic services also
to SUs that are not yet defined in the system. It may also be used as a temporary
operation mode during SUs installation phase.
In both modes, defined services are provisioned to defined SUs. The difference
between the two modes is in provisioning of services to SUs that are not defined in
the system.
In Advanced Mode, an undefined SU that is authenticated by the system will be
added to the database of the NPU (NMS) as Temporary. The database will include
also its MAC address and the configured registration parameters. No services are
provided as long as the SU is defined as Temporary. To receive services, the SU
