Near-end NAT
Near-end NAT defaults to disabled. If it is enabled, the contact IP address contained in
SIP messages sent out by SBC300 will be turned into the outbound IP address of public
network.
If NAT is enabled, you need to fill in the outbound IP address of public network.
Rate Limit
The maximum RPS(registrations per second), CPS(calls per second) and total call
volume of the access SIP trunk. Please refer to3.4.5
Codec
The codecs that the access SIP trunk supports. Please refer to 3.4.7
Blacklist
Select a blacklist for the access SIP trunk. Calls given by the caller numbers on the
blacklist cannot be routed by the access SIP trunk. Please refer to 3.4.6
Whitelist
Select a whitelist for the access SIP trunk. Calls initiated by the caller numbers on the
whitelist will be directed by the access SIP trunk. Please refer to 3.4.6
If no black list and white list are selected for the access SIP trunk, all calls can be routed
by the access SIP trunk.
Inbound
Manipulation
Select a number manipulation rule or a number pool for the access SIP trunk. When a
call routed by the SIP trunk matches the manipulation rule, its number will be
manipulated. Please refer to 3.4.8 and 3.4.9
DTMF
DTMF is short for Dual Tone Multi Frequency;
There are three DTMF modes, including SIP Info, Inband, RFC2833;
If the DTMF mode of an access SIP trunk differs from that of core network, SBC300
will convert it through DSP
Inbound
SIP
Header
Manipulation
Select a SIP header manipulation rule for inbound calls of the access 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 access SIP trunk.
Please refer to 3.4.10
Outbound
SIP
Header
Manipulation
Select a SIP header manipulation rule for outbound calls of the access 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 access SIP trunk.
Please refer to 3.4.10
Trunk Mode
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’.
