My waitforsilence command has been working fine as far as I know, but now I see it breaking through when I view the CLI. I went into the debug logs and saw the errors that come from this section of code in waitforsilence.
When I do a test call, I can hear asterisk talk to me after it breaks through. Using SIP channel g729 codec.
Can anyone elaborate for me about this error condition - what is means, why it occurs, what you have done to fix it? Thanks!
00093 /* Await silence... */
00094 f = NULL;
00095 for(;;) {
00096 res = ast_waitfor(chan, 2000);
00097 if (!res) {
00098 ast_log(LOG_WARNING, "One waitfor failed, trying another\n");
00099 /* Try one more time in case of masq */
00100 res = ast_waitfor(chan, 2000);
00101 if (!res) {
00102 ast_log(LOG_WARNING, "No audio available on %s??\n", chan->name);
00103 res = -1;
00104 }
00105 }
I changed from a sip channel to IAX thinking for some reason I was getting one way audio even though regular phone calls go through ok. I read that this app has a problem with digital silence as well. Anyway, the error I had before goes away with IAX, but now I get timeout after only seven seconds. Any ideas?

I changed to using BackgroundDetect with gsm (was g729) and it worked great. The tried WaitforSilence with gsm and worked great.
Odd thing is, I retried WaitforSilence with g729 and it worked. So I am back to where I started and have not been able to reproduce the error. Perhaps it is a g729 issue that is intermittent. Any thoughts?
