Sounds like your SIP client is behind NAT and you need nat=yes in sip.conf, and/or you need to enable STUN support in your SIP client so that the correct sender IP address. Note that SIP clients can only register with Asterisk if you have set host=dynamic and you have type=friend or type=peer set. > How should I attack the problem? First collect and provide meaningful information incl. sip.conf 1. Is NAT between the SIP phone and Asterisk? Does your SIP client use STUN? Which SIP client do you use? 2. Is Asterisk itself behind NAT? If yes first try to run Asterisk without NAT. 3. Does it work if you use a IAX client instead of a SIP client? > What debugging tools exist to try to determine why Asterisk is not > accepting the registration requests? - at the CLI enter SIP DEBUG (and SIP NO DEBUG when done) - press F9 if your client is X-Lite - you can use ethereal for more details, however usually the above two tools should already be sufficient Philipp _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
