Call Logging All inbound and outbound SIP sessions that cross the multi-media SIP PBX can be
monitored from the SpeedTouch™web interface. This is a useful tool to supervise the
SIP communications involving your LAN User Agents.
Call Screening To increase SIP communications security, it may make sense to block sessions
originating from either side of the network that are associated with particular users,
on account of fraud, abuse, and so forth. Therefore, the SpeedTouch™ SIP PBX
policy logic analyses the From/To field in SIP INVITEs messages, comparing the URI
with a list of undesirables, and if it finds a match returning a 403 Forbidden message
and refusing to pass the signalling along.
More precisely, the SpeedTouch™ SIP PBX includes an outbound session screening
feature. It allows the subscriber to prohibit outbound sessions, through the use of an
outbound black list, configurable via the Call Screening pages.
In a similar way, inbound sessions can be controlled by the inbound session
screening capability of the SpeedTouch™ SIP PBX. This allows the subscriber to
restrict inbound sessions originating from users configured an inbound black list.
