43.6.2 SIP Interfaces
A SIP Interface represents a single SIP signaling entity, which is a combination of
UDP, TCP, and TLS ports relating to a single specific IP address (in the control
subnet). The SIP Interface is configured with a SRD. This allows User Agents on the
network to communicate with a specific SRD, using the SIP Interface associated with
it.
Refer to the 'SIP Interfaces Table' on page 630 for a detailed description of the SIP
Interfaces table and its configuration.
The figure below illustrates the SBC application call flow between an enterprise LAN
(IP PBX) and an ITSP (WAN), implementing different interfaces (IP addresses and
ports) for RTP packets and SIP signaling.
