SIP Proxy Settings Configuration Parameters

ItemDescription
Outbound Proxy Server AddressDefine the Outbound SIP Proxy Server Address.
Outbound Proxy Server PortDefine the Outbound SIP Proxy Server Port. 
List of SIP Servers

Lists the SIP Servers that the EdgeMarc can failover to. To manually enter the list, click Create.
See Adding New SIP Server to add a new SIP server to the list.

Outbound Proxy Server TransportConfigure Outbound Proxy server transport for SIP signalling. The options are UDP, TCP and TLS.
Enable SRTPEnabling this option provides SRTP media encryption. This option is available only for TLS transport.
SIPUA TLS Settings
PortThe port on which this device listens for SIP over TLS connection requests.
TLS Protocol

Select the required TLS protocol method from the drop-down list:

  • TLSv1.2 – Only allow TLS version 1.2 protocol (RFC 5246). When selected, connections from endpoints with earlier TLS versions are rejected.  
  • TLSv1.3 – Only allow TLS version 1.3 protocol (RFC 8446). When selected, connections from endpoints with earlier TLS versions are rejected.  
Ciphers String

Adds or restricts the cipher suites offered by this device during a TLS handshake.

Some examples are:

  • TLSv1.2
    All cipher suites from TLS version 1.2 specification.
  • TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256:TLS_AES_128_GCM_SHA256
    TLSv1.3 cipher suites

Interface

Provides options to select the interface policies.

Certificate

Select the X.509 certificate for the interface in PEM format. Select the required certificate from the options in the drop-down list. 

Note: Make sure that the common name (CN) in the certificate matches the domain name or IP of the interface.

Policy

Select the peer certificate verification policy from the drop-down list:

  • No check – The peer certificate is not verified.
  • Verify if provided – Send a client certificate request to clients but continue handshake if the client does not return a certificate. Fail if the certificate is returned and the verification fails.
  • Require and Verify – Send a client certificate request to clients and continue only if the client sends a certificate and the certificate verification succeeds.
  • Require and Verify Once – Send a client certificate request to clients and continue only if the client sends a certificate and the certificate verification succeeds. Client certificate requests are not sent during renegotiation.

Add New SIP Server

The system supports auto-failover to secondary SIP servers - if it is provided with a list of SIP servers.

In normal IAD mode, you are required to provide IP addresses of the SIP servers, not DNS addresses. But in IAD with geo-redundancy mode, you can specify either IP addresses or FQDNs of the SIP Servers.

To add a new SIP server to the list:

  1. Choose SIP UA > SIP Proxies.

  2. To manually enter the list click Create, adjacent to the List of SIP Servers. The GUI will change to present a window for adding and viewing SIP Server details.

  3. Enter the following details and click Add:

    • IP Address: Enter the IP address/FQDN of the SIP Server.

      Note

      FQDN is supported only in IAD mode with geo-redundancy. If your EdgeMarc 300 device is ATA licensed, IAD mode and geo-redundancy mode are enabled by default.

    • Port: Enter the port of the SIP Server

      Note

      URLs are not allowed in these fields.
