8.5 LANPBX.CFG configuration file
The xBS downloads the lanpbx.cfg file from the embedded CS TFTP server. This file contains the IP
addresses of the CS.
It is exactly the same lanpbx.cfg file as for ALE IP-Phones.
8.6 xBS firmware binary
The xBS firmware binary (binipxbs) is delivered with the call server binary package. The
xBS is using TFTP to retrieve this file during start-up. The deployment of a new firmware
binary will be done on all the xBS. It is possible to forbid the upgrade on a specific xBS via
its WBM interface (nevertheless it is highly recommended that all the xBS in a deployment
have the same FW release). The firmware binary file is signed.
8.7 QoS
QoS mechanisms must be used for implementing an optimum VoIP architecture. QoS policy
must be deployed across the whole data network (including the switches and routers).
For an optimum audio quality, the network round trip delay, the packet jitter, the packet loss
rate must be known and bounded. For example, a round trip delay less than 150ms, jitter
less than 20ms and packet loss less than 1% will allow a very good audio quality (subjective
MOS score of 4).
QoS L2 and L3 Type of Service (ToS) /Differentiated Services Code Point (DSCP) /
Differentiated Services DiffServ can be configured in the Call Server. The defined values will
be given by the CS to the xBS during its initialization.
IEEE 802.1 p/q (same value for voice and signaling flows) can be configured on CS server
and on xBS.
TOS/Diffserv tagging (same value for voice and signaling flows) can be configured on CS
server and xBS.
