There are three DTMF modes, including SIP Info, Inband, RFC2833;
If the DTMF mode of an core SIP trunk differs from that of access network, SBC300
will convert it through DSP
Inbound
SIP
Manipulation
Select a SIP header manipulation rule for inbound calls of the core SIP trunk. If a call
matches the manipulation rule, the SIP header of the messages related to the call will be
manipulated when it comes into the core SIP trunk.
Please refer to 3.4.10
Outbound
SIP
Manipulation
Select a SIP header manipulation rule for outbound calls of the core SIP trunk. If a call
matches the manipulation rule, the SIP header of the messages related to the call will be
manipulated when it goes out the core SIP trunk.
Please refer to 3.4.10
Server IP Type
When SBC is connected to IMS,
Static
: you need to manually configure the IP address and port of the peer device, for
example, 192.168.2.159:5060
Remote domain name: the domain name of the peer
Dynamic
: the access SIP trunk works as a server, and you need to configure username,
authentication ID and password for the SIP trunk, which will be used when a peer device
tries to register to the SIP trunk. If the peer device registers to the SIP trunk successfully,
the status of the SIP trunk will be ‘True’. If the peer device fails to register or does not
register to the SIP trunk, the status of the SIP trunk will be ‘Flase’.
Registration
When ‘Server IP Type’ is configured as ‘Static’, registration will be displayed.
If registration is enabled, the core IP trunk will be registered to the configured peer
address and port, and the status of the core SIP trunk will become ‘Ture’. Otherwise, the
status is ‘False’. For the status of core SIP trunk, please refer to 3.3.4 .
Keepalive
If ‘Keepalive’ is disabled, the system will not detect whether the core SIP trunk’s peer
device (generally it is the core network server) is reachable or not.
If it is enabled, option message will be sent to detect the core network server is reachable.
If response is received, it means the core network server is reachable, and the status of
the access SIP trunk is ‘True’. Otherwise, the status will be ‘False’. For the status of
access SIP trunk, please refer to 3.3.3 .
Times of No
response
The maximum number of timeouts for receiving response from the core network server
after option messages are sent out.
Interval
The interval to send option message to the core network server
SIP
Session
Timer
Session timer is a mechanism to keep activating sessions.
If ‘Supported’ is selected, SBC300 will send ‘reinvite’ messages to keep activating
sessions within the configured duration.
If no messages are detected within the configured duration, sessions will be considered
