Device Configuration

There are thousands of SIP devices on the market, for how to configure them we advise you to consult the support forum of the device manufacturer.

Please do not open a ticket related to how a particular device must be configured.

Setup your SIP device as follows:

Account Credentials

Account credentials are used for authentication and authorization of SIP requests performed by the SIP device.

Username XXX
Password YYY
Domain/Realm sip2sip.info
  • Always Register must be On
  • Set the Registration refresh interval to 600 seconds
  • There are multiple servers available in multiple locations. To locate them, the SIP device must always perform DNS lookups as defined in SIP standard RFC3263.

Specific SIP devices configuration

Outbound Proxy

The following details may change over time, please use DNS 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


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

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

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.

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.
