Configuration Terms Description
means whether the SRD's resources (SIP Interfaces, IP Groups, and
Proxy Sets) can be used by other SRDs. For example, if all tenants route
calls with the same SIP Trunking service provider, the SRD of the SIP
Trunk would be configured as a Shared Sharing Policy. SRDs whose
resources are not shared, would be configured with an Isolated Sharing
Policy.
IP Profile The IP Profile is an optional configuration entity that defines a wide range
of call settings for a specific SIP entity (IP Group). The IP Profile includes
signaling and media related settings, for example, jitter buffer, silence
suppression, voice coders, fax signaling method, SIP header support
(local termination if not supported), and media security method. The IP
Profile is in effect, the interoperability "machine" of the device, enabling
communication between SIP endpoints that "speak" different call
"languages".
The IP Profile is associated with the SIP entity, by assigning the IP Profile
to the IP Group of the SIP entity.
Classification Classification is the process that identifies the incoming call (SIP dialog
request) as belonging to a specific SIP entity (IP Group).
There are three chronological classification stages, where each stage is
done only if the previous stage fails. The device first attempts to classify
the SIP dialog by checking if it belongs to a user that is already registered
in the device's registration database. If this stage fails, the device checks
if the sou
rce IP address is defined for a Proxy Set and if yes, it classifies it
to the IP Group associated with the Proxy Set. If this fails, the device
classifies the SIP dialog using the Classification table, which defines
various characteristics of the incoming dialog that if matched, classifies
the call to a specific IP Group. The main characteristics of the incoming
call is the SIP Interface that is associated with the SRD for which the
Classification rule is configured.
IP-to-IP Routing IP-to-IP routing rules define the routes for routing calls between SIP
entities. As the SIP entities are represented by IP Groups, the routing
rules typically employ IP Groups to denote the source and destination of
the call. For example, to route calls from the IP PBX to the SIP Trunk, the
routing rule can be configured with the IP PBX as the source IP Group
and the SIP Trunk as the destination IP Group.
Instead of IP Groups, various other source and destination methods can
be used. For example, the source can be a source host name while the
destination can be an IP address or based on an LDAP query.
Inbound and Outbound
Manipulation
Inbound and Outbound Manipulation lets you manipulate the user part of
the SIP URI in the SIP message for a specific entity (IP Group). Inbound
ma
nipulation is done on messages received from the SIP entity; outbound
manipulation is done on messages sent to the SIP entity.
Inbound manipulation lets you manipulate the user part of the SIP URI for
source (e.g., in the SIP From header) and destination (e.g., in the
Request-URI line) in the incoming SIP dialog request. Outbound
manipulation lets you manipulate the user part of the Request-URI for
source (e.g., in the SIP From header) or destination (e.g., in the SIP To
header) or calling name, in outbound SIP dialog requests.
The Inbound and Outbound manipulation are associated with the SIP
entity, by configuring the rules with incoming characteristics such as
source IP Group and destination host name. The manipulation rules are
also assigned a Routing Policy, which in turn, is assigned to IP-to-IP
