In this section:
The SBC Core platforms (SBC 5000 series, SBC 7000, SBC SWe) listen to the TCP/IP network ports listed in the following tables. Some of these ports will not be open if the corresponding product features are not configured.
The actual ports that the SBC listens to depends on the actual system configuration.
Due to an IPMI vulnerability, Sonus recommends not connecting the BMC Ethernet port to an external network unless the network is deemed well-protected.

If a zone's sipSigPort
is configured for transportProtocolsAllowed = sip-tls-tcp
, and either Egress IPSP Transport Type is TLS Over TCP and/or the Egress TG’s transportPreference is tls-tcp, the SBC increments the configured portNumber
by 1 and uses it as the new port number for SIP over TLS signaling. The SBC then opens a TCP socket for SIP over TLS for the new TCP port number.
Example: When sipSigPort
is configured with a portNumber
of 5060 and transportProtocolsAllowed = sip-tls-tcp
, the SBC listens on TCP port 5061 for SIP over TLS.
