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
• You may use TLS transport, the server has a valid certificate issued by RapidSSL
• 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¶

We use a variable numbers of geographically distributed SIP servers. 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

XCAP Root¶

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

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.
