Click the Create SIP Profile (
) icon at the top of the SIP Profile View page.Create SIP Profile
The options in the Session Timer panel control the timers used to verify that the current SIP session is still valid.
Specifies whether or not to use the session timer to verify the SIP session. The remainder of the options in this panel are only visible of the Session Timer is Enabled (default).
Specifies the minimum value to use for incoming session refresh in seconds. If the SBC Edge (SBC) negotiates a session refresh this value will be used to indicate the minimum value acceptable for a session refresh. Default: 600.
Specifies an interval, proposed to a SIP peer, to use for a session refresh. At each interval, a session refresh occurs, if the remote does not respond the call is disconnected. Default: 3600.
Controls how the SBC responds if the session refresher fails. Default: False.
The options in the Header Customization panel determine how certain headers in the SIP protocol are handled, what content from certain headers is used, and more.
Specifies the contents of the SIP User-Agent header. Default: Ribbon SBC EDGE.
Specifies which, if any, Fully Qualified Domain Name (FQDN) is used in the From header.
FQDN in From Header will not function if the Host Name and/or Domain Name is not configured in System | Node-Level Settings.
Determines (Enable/Disable) whether FQDN (Fully Qualified Domain Name) is included in the Contact Header. Default: Disable. Available options: Disable, SBC FQDN or Static.
Specifies the host portion to be used in the From or Contact Header. This field is displayed only when the FQDN in From Header or FQDN in Contact Header field is set as Static. Valid entry: FQDN[:port], IP4[:port], [IP6]:port or IP6. An example of an IPv6 entry is: [fd00:10:6b56:226::204]:27526.
When enabled (set as Always), the SBC always sends a P-Asserted-Identity header in the outbound INVITE message. When the SBC receives an inbound INVITE message with a P-Preferred-Identity or P-Asserted-Identity header, the information from that header is used in the outbound P-Asserted-Identity header. However, when the SBC receives a Privacy header, the identity is revealed in the outbound INVITE based on privacy header value.
When disabled, privacy information in the outbound INVITE is sent depending on the configuration of the Trusted Interface and the Privacy Pass-through Header. Default: Trusted Only.
Specifies if the X-SBC Edge -Diagnostics header is added to the outbound SIP signaling messages. This header indicates detailed diagnostic information about the call (such as media mode, DSP/RTP-Proxy/Direct etc.).
Options: Enable (default)(header is included), or Disable (header is not included).
Example: In a Direct Media scenario, the SBC is only anchoring SIP Signaling and the media failures are outside of the control of SBC. In this case, the following header message is included:
X-SBC EDGE-Diagnostics: SBCInternal;cid=124;media-mode="audio:Direct video:Direct".
This header tells the peer device that the SBC has used direct media mode.
When enabled (default), the SBC passes the Display Name (Calling Name), P-Asserted-Identity and Privacy header information from the inbound INVITE to the outbound INVITE message. The User-Agent header is also present.
When disabled, the Display Name (Calling Name), PAI/PPI and Privacy headers are not passed, and the User-Agent header is suppressed.
Enables SIP to use Calling Number and Name from FROM header always. By default, if P-Asserted-ID/P-Preferred-ID are present, Calling Number and Name are derived from P-Asserted-ID/P-Preferred-ID headers. Valid entry: From RFC Standard (default) or "From" Header only.
Determines which SIP Header to use in SIP call. Valid entry: First or Last (default).
Determines which technical specification needs to be used to process Record-Route header. Choices: ETSI or RFC 3261(default).
The options in this panel determine the duration of timers that control the behavior or SIP transmissions.
Specifies the interval, in milliseconds, for which new TCP/TLS connections over SIP can be tried when no response is received from far end. Default: 5000.
Specifies the maximum number of retransmissions of client transaction messages over UDP. The default value disables this feature and maximum retransmissions are then controlled by Timer B and Timer F values. Any non-zero value modifies Timer B and Timer F and retransmissions are controlled by the selected value. Default: RFC Standard.
Redundancy Retry Timer
Specifies the time, in milliseconds, before the REGISTER retry is sent to the primary SIP Server after the REGISTER re-transmission has been not been responded to by both primary and secondary SIP Servers.
Valid entry: 5000 - 180000 ms. Default entry: 180000 ms.
Enter an integer value for each of the timers, if other than standard defaults are required.
Timer | Default Value | Meaning |
---|---|---|
T1 | 500 ms | Round-trip time (RTT) estimate |
T2 | 4000 ms | Maximum retransmission interval for non-INVITE requests and INVITE responses |
T4 | 5000 ms | Maximum duration that a message can remain in the network |
J | 4000 ms | Maximum time to wait when the server transaction enters the "Completed" state. |
D | 32000 ms | Wait time for response retransmissions |
Transport Timeout Timer | 5000 ms | Determines the duration of time to wait before ending a tired connection when far end blocks the connection. |
The MIME Payload contains location information about the origin of the call. The SBC processes the Multi-part MIME Content-Type header in the SIP INVITE message upon ingress to the Signaling Group. The SBC passes through the pidf+xml Content-Type as is to the egress side Signaling Group in an SIP INVITE message. The SBC does not process the XML body of the PDIF-LO content.
ELIN identifier maps the selected label from PIDF-LO XML content to the call router translation table input field. Default value: LOC.
Specifies whether or not to allow the passthrough of pidf+xml content from Ingress to Egress.
Specifies whether or not to allow the passthrough of unknown subtype content from Ingress to Egress. Default value: Disable.
The SIP Option Tags determine in which SIP header, the 100rel (Default: Supported), Path (Default: Not Present), Timer (Default: Supported) and Update (Default: Supported) tags will appear.
When the Session Timer option is enabled, the SBC uses either INVITE or UPDATE to refresh the session. The method used is negotiated between the SBC and peer. The Option Tags selections simply specify in which header to specify the tag.
The SDP customization fields enables you to customize configuration for SDP. The features in this section are applicable only when a DSP is in use for the call.
For interoperability purposes, enables the /1 field to be removed from media attribute in SDP. In the a= line, the /1 field is dropped if the value is configured as False.
Example: a=rtpmap:4 g723/8000/1 becomes a=rtpmap:4 g723/8000
Valid entry: True (/1 field stays intact) or False (/1 field is dropped). Default value: False.
Determines if the Connection Data (represented by "c=") is present in both the Session and Media sections of the SDP. Some endpoints are unable to handle the "c=" in the media section. Valid entries: True (the "c=" is included in the media section) or False (the "c=" does not appear in the media section). Default entry: True.
Value of the Origin (o=) username field. Valid entry: up to 64 alphanumeric characters. For security purposes, this field can be set as "-". Default value: SBC.
Value of the Session (s=) field. Valid entry: up to 64 alphanumeric characters. For security purposes, this field can be set as "-". Default value: VoipCall.
Determines how digits are sent to the far end during an ongoing call (Example, digits might be sent to an IVR system during a call). This argument specifies which digit transmission method to use when both are available to the call.
