Appendix A. More About SIP

You can do this by using the Ingate Startup Tool, which can be downloaded from

http://www.ingate.com/Startup_Tool.php. Below you ﬁnd the conﬁguration that should be

made manually if you do not use the Tool.

Go to the Basic Settings page under SIP Services and switch the SIP module on.

Go to the Routing page under SIP Trafﬁc. In the DNS Override For SIP Requests table,

add a row where you enter your SIP domain as the Domain, and enter your PBX/registrar IP

address and port. You can also select which transport should be used when forwarding SIP

requests to the PBX.

If you have remote users behind NAT boxes, you also need to conﬁgure Remote SIP Con-

nectivity under SIP Services. Use the built-in STUN server and/or the Remote NAT Traver-

sal. It is recommended to use the Remote NAT Traversal, as it works for more clients and

more NAT types.

Finally, go to the Save/Load Conﬁguration page under Administration and apply the new

settings by pressing Apply conﬁguration.
