Outbound proxy

Outboud proxy

proxy.sipthor.net

Though optional, is recommend that you always use the outbound proxy setting as this helps the NAT traversal and your device remains always reachable.

XCAP root

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

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.

'''NAT traversal'''

Practically you do not need to set anything special in the client, NAT traversal is solved automatically by the SIP2SIP server infrastructure. We recommend actually that you check to have disabled all client features related to NAT traversal:

1. Disable any keep-alive technique like PING, NOTIFY, OPTION, CR/LF or STUN
 1. Disable any SIP ALG support in the border router, most of the so called 'SIP enabled' routers on the market today are [http://www.voip-info.org/wiki/view/Routers+SIP+ALG simply broken]
 1. Disable voice activation detection (VAD) in your device
