SIP User's Manual 184 Document #: LTRT-12801
MP-500 MSBG
Parameter Description
TLS Port
[SIPInterface_TLSPort]
Determines the listening TLS port.
The valid range is 1 to 65534. The default is 5061.
Note: This port must be outside of the RTP port range.
SRD
[SIPInterface_SRD]
Determines the SRD ID (configured in the 'SRD' table)
associated with the SIP Interface.
The default is 0.
Note: Each SRD can be associated with up to three SIP
Interfaces, where each SIP Interface pertains to a different
Application Type (GW/IP2IP, SAS, and SBC).
3.4.5.8.4 Configuring the Classification Table
The 'Classification Table' page allows you to configure rules for classifying incoming SIP
dialog initiating requests (e.g. SIP INVITE message). The classification identifies the
incoming SIP dialog request as belonging to a specific IP Group (from where the SIP dialog
request originated). The 'Classification' table is used to classify the SIP dialog request only
after the other classification methods (device's Registration database and Proxy Set-based)
have failed.
Classification begins in the device's Registration database, where it searches for a match
by checking if the request arrived from a registered user:
„ Compares received Contact to the Contact of the registered user
„ Compares P-Asserted/From URL to the registered AOR
If the database search is unsuccessful, the classification process proceeds with locating a
Proxy Set (associated with the SIP dialog request’s IP address) and then finding a match
with a corresponding IP Group in the 'IP Group' table. Each IP Group can be classified
according to its Proxy Set (if in the 'IP Group' table the parameter ClassifyByProxySet is
enabled). If enabled, the device classifies Requests arriving from the IP Group’s Proxy Set
as coming from this IP Group. The classification is done according to the Proxy IP list (in
case of host names, then according to the dynamically resolved IP address list). Note that
this classification is not relevant in cases where multiple IP Groups use the same Proxy
Set.
If classification based on Proxy Set is unsuccessful, the device proceeds to the
'Classification' table, which searches for a source IP Group based on the following matching
rules: Source IP Address, Source Username Prefix, Source Host Prefix, Destination
Username Prefix, Destination Host Prefix, and Source SRD.
If the above classification process fails to determine the source IP Group to which the
incoming packet belongs, the call can either be rejected, or allowed and processed (by
assigning it to the default IP Group of the default SRD). This last classification is
determined by the parameter AllowUnclassifiedCalls.
This IP Group is afterwards used for the following purposes:
„ Input for the manipulation and routing processes
„ Defining SIP behavior and IP Profile, Media realm and matching account
