Here are some tips for using SIP behind a firewall and with NAT.

 

 

1. Use an external STUN server. You can install your own instance or use the existing STUN Server at

www.sipphone.com. It can be access on stun01.sipphone.com on port 3478.

 

2. Use asterisk as outbound proxy/registrar. Configure its asterisk's account to "nat" type.

 

3. The easiest way is to get free SIP account on any of free public SIP registrar - sipphone.com or similar.

Use this registrar as outbound proxy. Configure STUN if it is required by registrar.
