Thanks Mike for the feedback. If a user has a problem using my FS server, I'll check what client they have. For those interested, here's what RFC 3581 adds to SIP: Session Initiation Protocol (SIP) operates over UDP and TCP, among others. When used with UDP, responses to requests are returned to the source address the request came from, and to the port written into the topmost Via header field value of the request. This behavior is not desirable in many cases, most notably, when the client is behind a Network Address Translator (NAT). This extension defines a new parameter for the Via header field, called rport, that allows a client to request that the server send the response back to the source IP address and port from which the request originated. -- View this message in context: http://old.nabble.com/IAX--Issues-connecting-road-warriors-with-SIP--tp26625105p26635842.html Sent from the Freeswitch-users mailing list archive at Nabble.com. ___ FreeSWITCH-users mailing list FreeSWITCH-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org
[Freeswitch-users] IAX? Issues connecting road warriors with SIP?
Hello In a thread back in March, I read that support for IAX in FreeSwitch is a bit of kludge and since there's not much demand for it, chances are it won't improve in the foreseeable future. So I'd like some feedback from users who routinely connect to a FreeSwitch server from various venues, ie. wifi hotspots at McD, Ethernet LAN in hotels, etc. (in my case, the FreeSwitch server is located in a private network behind a NAT router with SIP/RTP ports statically mapped.) Do you sometimes/often get issues where SIP (UDP5060) or RTP (UDPwhatever) ports fail being opened dynamically to work properly, or does SIP today really work well over NAT firewalls? Thank you. -- View this message in context: http://old.nabble.com/IAX--Issues-connecting-road-warriors-with-SIP--tp26625105p26625105.html Sent from the Freeswitch-users mailing list archive at Nabble.com. ___ FreeSWITCH-users mailing list FreeSWITCH-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org

with the right clients, it nearly always works well. with a client that does not support stun or at least rfc 3581 the results are much more sketchy and require more hacks on the server side, but with enough effort can almost always be made to work.

Do you sometimes/often get issues where SIP (UDP5060) or RTP (UDPwhatever) ports fail being opened dynamically to work properly, or does SIP today really work well over NAT firewalls? Yes I get issues quite a bit with the server being behind a firewall. IAX is much nicer in this circumstance. ___ FreeSWITCH-users mailing list FreeSWITCH-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org

I just set up an IPv6 over IPv4 tunnel and nat goes away. I have native IPv6 over ADSL now, as part of a trial that my ISP is conducting. As a result, one end of the conection doesn't go through a tunnel provider anymore. Given the problems I've had (and still have) with nat, I want to be rid of it as much as possible. Nevertheless, I agree that in a nat scenario, IAX can be easier to configure correctly. ___ FreeSWITCH-users mailing list FreeSWITCH-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org
