Setup your SIP application software or hardware device as follows:

General || Username || XXX|| || Password|| YYY|| || Domain||sip2sip.info|| || Outboud proxy ||proxy.sipthor.net||

Replace XXX with your username and YYY with your password received during the registration of your SIP account.

We recommend that you:

1. Set the SIP Registration refresh interval to 600 seconds
 1. Disable any keep-alive technique in the client (like pings, NOTIFY or STUN)
 1. Disable any SIP support in the border router

MSRP relay

If you use SIP SIMPLE instant messaging based on MSRP, a relay is available for helping traverse the NAT. You need to use the relay if you are the receiving party and you are behind a NAT-ed router. The MSRP relays can be found in the DNS by using SRV lookup for _msrps._tcp.sip2sip.info.
