4.3.3 Configuring SIP Signaling Interfaces
A SIP Interface consists of a combination of ports (UDP, TCP, and TLS) associated with a
specific IP network interface. The SIP Interface is associated with an SRD.
The procedure below shows how to add SIP interfaces. In the example scenario, an
internal and external SIP interface must be added for the E-SBC.
To add SIP interfaces:
1. Open the SIP Interface Table page (Configuration tab > VoIP > Control Network >
SIP Interface Table).
2. Add a SIP interface for the LAN:
a. Click Add.
b. Configure these parameters:
Parameter Example Setting
Index "1"
Network Interface "Voice" (for IPv4) / "IP6Voice" (for IPv6)
Application Type
SBC
TLS Port "5067"
TCP and UDP "0"
SRD "1"
c. Click Submit.
3. Add a SIP interface for the WAN:
a. Click Add.
b. Configure these parameters:
Parameter Example Setting
Index "2"
Network Interface "WANSP" (for IPv4) / "IP6WANSP" (for IPv6)
Application Type
SBC
UDP Port "5060"
TCP and TLS "0"
SRD "2"
c. Click Submit.
The configured SIP Interface table is shown below:
