本文发表在 rolia.net 枫下论坛I have set up an Asterisk server on my LAN and want to connect to our IAX service provider. (My environment is: asterisk 1.8.10.1, centos 5 with kernel 2.6.18-308.1.1.el5PAE and my firewall have opened udp 4569 for IAX2) however, when I type "iax2 show registry" at console, it shows unregistred. when I turn on debug on and I got these:
