Setup your SIP device as follows:

h2. Outbound Proxy

We

The following details may change over time, please use a variable number of server distributed geographically. You should never set manually an IP address into your SIP device. You must use proper DNS lookups (NAPTR + SRV + A lookups) instead of hardwiring these setting into your SIP device.

| Host | Port | Protocol |
| proxy.sipthor.net| 5060| UDP |
| proxy.sipthor.net| 5060| TCP |
| proxy.sipthor.net| 5061| TLS |

h2. XCAP Root



If you use SIMPLE presence you need to set XCAP root:

| XCAP Root | https://xcap.sipthor.net/xcap-root/| https://xcap.sipthor.net/xcap-root@sip2sip.info/ |

h2. MSRP Relay



If you use 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.

h2. STUN Servers

You may use STUN for ICE NAT traversal. The STUN servers can be found in the DNS by using SRV lookup for _stun._udp.sip2sip.info.
