Features within a SIParator allow you to create filter rules to block individuals from using your network.; you can also specify what ports to use, and it would be easier to spoof SUBSCRIBE and NOTIFY without the SIParator in place; you can filter requests based on the contents of the From and To SIP headers. Requests that do not match any rule are handled according to the DEFAULT HEADER FILTER POLICY. You can use the wildcards * (match any number of characters) and ? (match a single character). The SIParator will only let through SIP packets that have one of the content types (MIME types) shown next:

If you have a home router that is a Firewall + NAT, make sure you have opened up the proper ports. You need to open up ports 5060 � 5070 and ports 8766 - 8775. If you're home router is solely a NAT, set the NAT to be a STUN server. |
STUN server Setting
If you have a phone that runs a STUN client, the SIParator is also a STUN server.
In this case, no ports need to be opened up on your NAT router. Use the STUN Server if you have STUN-aware SIP clients. Two public IP addresses are needed at a minimum.
...
There is a parameter setting with the SIParator GUI environment to turn STUN server function: On, shown next:<center>
</center>
Remote NAT Traversal
If the SIP client is not STUN capable, you can use the built in Remote NAT traversal feature of the SIParator. The SIP client needs to re-Register or respond to OPTIONS packets rather often for this to work.<center>

If you are using NAT, you also need to set the PHONESET_EXTERNAL_IP_ADDRESS to the public IP address of your NAT router.

You can also use your SIParator as an SBC to allow communication between your sipXecs system and an ITSP (SIP Trunk) on the Internet to connect to the PSTN.
See HowTo configure a SIP TrunkTrunking section for how to configure your sipXecs system to route calls via the SIParator to reach the ITSP on the outside network.
