sipInteropSymmetricUdpSourcePortEnable

Indicates whether the unit always uses the same local port when sending SIP
traffic over UDP.
          
Symmetric UDP ports are sometimes needed to traverse NAT/Firewall devices.
          
Note that when changing this setting, all destinations are automatically thrown
out of the penalty box, when applicable.
          
enable :
   SIP signaling sent over UDP originates from the same port as the port on which
   the user agent is listening. This is configured in MX-SIP-MIB's sipPort
   variable. When enabled, ICMP messages are not processed, which means that
   unreachable targets will take longer to detect.
          
disable :
   SIP signaling over UDP uses a randomly-generated originating port. ICMP
   errors are processed correctly.
          
This variable's semantics are different depending on the software version.
Please refer to the documentation shipped with your device for more
details.
