Hi guys, I just installed the asterisk and the h323 modules. The h323 module seems works well, because the asterisk show the options to handle it. Now I trying to do a simple test, I have a mediatrix with the adress 10.11.2.121 with two phones 1001 and 1002. And I wanna make calls one to another. Then I configure the h323.conf file: [general] port = 1720 bindaddr = 0.0.0.0 context = default allow=all ; turns on all installed codecs dtmfmode=rfc2833 And the extension.conf file: ...[general] and [global] statements [default] exten => _1001,1,Dial(H323/10.11.2.121) exten => _1002,1,Dial(H323/10.11.2.121) But when I try use the phones to talking I don`t listen the ring. How I just start with asterisk I thinked that my confiuration is wrong. Someone have some idea??!! Thanks all. Giscard _______________________________________________________ Yahoo!
