Interoperability with 3rd Party SIP endpoints

Interoperability with 3rd party endpoints not supporting ICE, such as PSTN gateways or soft switches, usually does not require additional integration work. An SDP description that does not contain any ICE candidates or contains ICE candidates in a format that does not comply with ICE RFC will still be parsed and processed by AnyFirewallâ„¢ Engine, using the IP address and port information found in the m/c line of the SDP received from the 3rd party end point.
