Hi, I use Asterisk 1.2. My configuration is: ooh323.conf: [general] port=1720 bindaddr=0.0.0.0 allow=all context=office tos=lowdelay iax.conf: [general] disallow=all allow=gsm bindport=4569 bindaddr=0.0.0.0 codecpriority=reqonly language=en jitterbuffer=yes tos=lowdelay [test] type=friend host=dynamic username=test secret=testpwd context=office callerid="Test User" <test> extensions.conf: [general] static=yes writeprotect=yes [globals] [default] [office] exten => s,1,Dial(IAX2/test) Client test is connected by idefisk. On every call from outside I see on Asterisk console: == Starting OOH323/10.10.10.10-ba85 at office,2687988,1 failed so falling back to exten 's' -- Executing Dial("OOH323/10.10.10.10-ba85", "IAX2/test") in new stack -- Called test -- Call accepted by 192.168.46.99 (format gsm) -- Format for call is gsm -- IAX2/test-2 is ringing -- IAX2/test-2 answered OOH323/10.10.10.10-ba85 At this moment I hear call sound in caller phone and hear nothing in answerer phone, so connection is not established. Why? -- Thanks, Eugene Prokopiev
