Configuration the SIP Interface

To configure the DoS protection for TCP/TLS connections on a SIP interface:

1. In Superuser mode, type configure terminal and press Enter.

   ORACLE# configure terminal

2. Type session-router and press Enter to access the system-level configuration elements.

   ORACLE(configure)# session-router

3. Type sip-interface and press Enter. The system prompt changes to let you know that you can begin configuring individual parameters.

   ORACLE(session-router)# sip-interface
   ORACLE(sip-interface)#

   From this point, you can configure SIP interface parameters. To view all sip-interface parameters, enter a ? at the system prompt.

4. max-incoming-conns—Enter the maximum number of simultaneous TCP/TLS connections for this SIP interface. The default value is zero (0) which disables any limit to the number of simultaneous TCP/TLS connections on this SIP interface. The valid range is:

   • Minimum—0

   • Maximum—20000

5. per-src-ip-max-incoming-conns—Enter the maximum number of connections allowed from an end point.The default value is zero (0). The default disables the parameter. The valid range is:

   • Minimum—0

   • Maximum—20000

     Note:

     To make this parameter effective, you need to set the realm’s access-control-trust-level to low or medium.
6. inactive-conn-timeout—Enter the time in seconds you want a connection from an endpoint discontinued. This provides protection from end points doing an initial registration without sending any messages. The default value is zero (0). The default disables the parameter. The valid range is:

   • Minimum—0

   • Maximum—999999999

7. Save and activate your configuration.
