sip-interface
This command configures the SIP Interfaces table, which lets you define SIP Interfaces. A SIP Interface represents a Layer-3 network in your deployment environment, by defining a local, listening port number and type (e.g., UDP), and assigning an IP network interface for SIP signaling traffic.
Syntax
(config-voip)# sip-interface <Index> (sip-interface-<Index>)#
|
Command |
Description |
|---|---|
|
Index |
Defines the table row index. |
|
additional-udp-ports |
Defines a port range for the device's local, listening and source ports for SIP signaling traffic over UDP and is used to assign a specific local port to each SIP entity (e.g., PBX) communicating with a common SIP entity (e.g., proxy server). |
|
additional-udp-ports-mode [always-open|open-when-used] |
Defines the mode of operation for the Additional UDP Port feature. |
|
application-type {gw|sbc} |
Defines the application for which the SIP Interface is used. |
|
block-un-reg-users {acpt-all|acpt-reg-users|acpt-reg-users-same-src|not-conf} |
Defines the blocking (reject) policy for incoming SIP dialog-initiating requests (e.g., INVITE messages) from registered and unregistered users belonging to the SIP Interface. |
|
cac-profile |
Assigns a Call Admission Control Profile. |
|
call-setup-rules-set-id |
Assigns a Call Setup Rule Set ID. |
|
|
Defines the SIP response code that the device sends if a received SIP request (OPTIONS, REGISTER, or INVITE) fails the SBC Classification process. |
|
enable-un-auth-registrs {disable|enable|not-conf} |
Enables the device to accept REGISTER requests and register them in its registration database from new users that have not been authenticated by a proxy/registrar server (due to proxy down) and thus, re-routed to a User-type IP Group. |
|
encapsulating-protocol {none|websocket} |
Defines the type of incoming traffic (SIP messages) expected on the SIP Interface. |
|
interface-name |
Defines a descriptive name, which is used when associating the row in other tables. |
|
max-reg-users |
Defines the maximum number of users belonging to the SIP Interface that can register with the device. |
|
media-realm-name |
Assigns a Media Realm to the SIP Interface. |
|
message-policy-name |
Assigns a SIP message policy to the SIP interface. |
|
network-interface |
Assigns a Control-type IP network interface to the SIP Interface. |
|
pre-classification-manset |
Assigns a Message Manipulation Set ID to the SIP Interface. |
|
pre-parsing-man-set |
Assigns a Pre-Parsing Manipulation Set to the SIP Interface. T |
|
sbc-direct-media {disable|enable|enable-same-nat} |
Enables direct media (RTP/SRTP) flow (i.e., no Media Anchoring) between endpoints associated with the SIP Interface. |
|
sctp-port |
Defines the local SCTP port on which the device listens for inbound SCTP connections (i.e., SIP signaling over SCTP). Note: The parameter is applicable only to Mediant 90xx and Mediant Software. |
|
sctp-second-network-interface |
Assigns an additional IP network interface (Control-type) to the SIP Interface, which serves as the secondary (alternative) local IP address for SCTP multi-homing. Note: The parameter is applicable only to Mediant 90xx and Mediant Software. |
|
srd-name |
Assigns an SRD to the SIP Interface. |
|
tcp-keepalive-enable {disable|enable} |
Enables the TCP Keep-Alive mechanism with the IP entity on this SIP Interface. |
|
tcp-port |
Defines the device's listening port for SIP signaling traffic over TCP. |
|
tls-context-name |
Assigns a TLS Context (SSL/TLS certificate) to the SIP Interface. |
|
tls-mutual-auth {disable|enable|not-configured} |
Enables TLS mutual authentication for the SIP Interface (when the device acts as a server). |
|
tls-port |
Defines the device's listening port for SIP signaling traffic over TLS. |
|
topology-location {down|up} |
Defines the display location of the SIP Interface in the Topology view. |
|
udp-port |
Defines the device's listening and source port for SIP signaling traffic over UDP. |
|
used-by-routing-server {not-used|used} |
Enables the SIP Interface to be used by a third-party routing server for call routing decisions. |

Example
This example configures SBC SIP Interface "ITSP" that uses IP network interface "Voice" and Media Realm "ITSP":
(config-voip)# sip-interface 0 (sip-interface-0)# interface-name ITSP (sip-interface-0)# network-interface Voice (sip-interface-0)# application-type sbc (sip-interface-0)# udp-port 5080 (sip-interface-0)# media-realm-name ITSP (sip-interface-0)# activate
