SIP User's Manual 592 Document #: LTRT-83310
Mediant 600 & Mediant 1000
Parameter Description
and its transport type is set to TCP or TLS. The device first sends a SIP
OPTION message to establish the TCP/TLS connection and if it
receives any SIP response, it continues sending the CRLF keep-alive
sequences.
[PingPongKeepAliveTim
e]
Defines the periodic interval (in seconds) after which a “ping” (double-
CRLF) keep-alive is sent to a proxy/registrar, using the CRLF Keep-
Alive mechanism.
The default range is 5 to 2,000,000. The default is 120.
The device uses the range of 80-100% of this user-defined value as the
actual interval. For example, if the parameter value is set to 200 sec, the
interval used is any random time between 160 to 200 seconds. This
prevents an “avalanche” of keep-alive by multiple SIP UAs to a specific
server.
A.8.2 Network Application Parameters
The SIP network application parameters are described in the table below.
Table A-30: SIP Network Application Parameters
Parameter Description
Signaling Routing Domain Table
Web: SRD Settings
EMS: SRD Table
[SRD]
This parameter table configures the Signaling Routing Domain (SRD)
table. The format of this parameter is as follows:
[SRD]
FORMAT SRD_Index = SRD_Name, SRD_MediaRealm,
SRD_IntraSRDMediaAnchoring, SRD_BlockUnRegUsers,
SRD_MaxNumOfRegUsers, SRD_EnableUnAuthenticatedRegistrations;
[\SRD]
For example:
SRD 1 = LAN1_SRD, Mrealm1, 0, 1, 15, 1;
SRD 2 = LAN2_SRD, Mrealm2, 0, 1, 15, 1;
Notes:
This table can include up to 32 indices (where 0 is the first index).
The following parameters are not applicable:
IntraSRDMediaAnchoring, BlockUnRegUsers, MaxNumOfRegUsers,
and EnableUnAuthenticatedRegistrations.
For a detailed description of the table's individual parameters and for
configuring the table using the Web interface, see 'Configuring SRD
Table' on page 191.
For a description on configuring ini file table parameters, see
'Configuring ini File Table Parameters' on page 84.
SIP Interface Table
Web: SIP Interface Table
EMS: SIP Interfaces Table
[SIPInterface]
This parameter table configures the SIP Interface table. The SIP
Interface represents a SIP signaling entity, comprising ports (UDP, TCP,
and TLS) and associated with a specific IP interface and an SRD ID. The
format of this parameter is as follows:
[SIPInterface]
FORMAT SIPInterface_Index = SIPInterface_NetworkInterface,
SIPInterface_ApplicationType, SIPInterface_UDPPort,
