8.4.1.4 SIP Normalization
The device supports SIP normalization, whereby the SBC application can overcome
interoperability problems between SIP user agents. This is achieved by the following:
Manipulation of SIP URI user and host parts
Connection to ITSP SIP trunks on behalf of an IP-PBX - the device can register and
utilize user and password to authenticate for the IP-PBX
8.4.1.5 Survivability
The device's SBC application provides two survivability features:
Routing calls to alternative routes such as the PSTN
Routing calls between user agents in the local network using a dynamic database
(built according to registrations of SIP user agents)
For an example of configuring SBC survivability, see ''Survivability and Alternative Routing''
on page
.
8.4.2
SIP Network Definitions
The device's SBC application can implement multiple SIP signaling and RTP (media)
interfaces. For a detailed description, see ''Multiple SIP Signaling/Media Interfaces
Environment'' on page
.
8.4.3
SIP Dialog Initiation Process
The device's SIP dialog initiation process concerns all incoming SIP dialog initiation
requests. This includes SIP methods such as INVITE, SUBSCRIBE, OPTIONS, REFER,
INFO, UNSOLICITED NOTIFY, MESSAGE, and REGISTER.
The SIP dialog initiation process consists of the following stages:
Determining Source and Destination URL (see ''Determining Source and Destination
URL'' on page
)
Classifying Source IP Group (see ''Source IP Group Classification'' on page
)
IP-to-IP Routing (see ''SBC IP-to-IP Routing'' on page
Manipulating IP-to-IP Inbound and Outbound SIP dialogs (see ''IP-to-IP Inbound and
Outbound Manipulation'' on page
)
For a description of the Registration process, see ''User Registration and Internal
Database'' on page
