asterisk users - Apr 2007 - No Incoming Ring Tone (Even with "r" option)

Hello,

I am using an incoming iax provider to bring calls to my server.  When
an incoming call comes in, the calling party does not hear a ring
tone.  I figured that this was no big deal, and that I just needed to
enable the "r" flag to dial.  This has not fixed the situation though.
 Just to try to make sure the line was being picked up properly, I
tried the following:

[inbound]
exten => number,1,Answer
exten => number,n,Background(vm-goodbye)
exten => number,n,Dial(SIP/bdesktop,60,tr)
exten => number,n,Hangup

In this case, the caller hears the vm-goodbye message, and then
silence (while the phone actually does ring).

Does anyone know why the "r" option might not be working?  The
incoming channel is iax, and obviously the phone terminating the call
is Sip.

Thanks,

--Brian

If you don't hear the default ringback then "r" almost never fixes
it.
Before a call is answered Asterisk uses "out of band" signaling and 
sends back a message to the device and the device provides the ringback 
tone.

Once a call is answered OOB signaling doesn't work so Asterisk has to 
play the audio of a ringback tone to the caller.

Asterisk figures out what the exact tones should be sending by looking 
at /etc/asterisk/indications.conf.  If you do not have that file 
(there's an indications.conf.sample in /path/to/src/asterisk/configs) 
then Asterisk won't know what to send back.

I recommend that you remove the "r" option, remove the Answer line, 
create an indications.con (the sample one seems to work just fine), and 
use Playback -- since you are not actually waiting for any DTMF, and add 
the |noanswer option.

Example:
   exten => number,n,Playback(vm-goodbye|noanswer)
