asterisk users - Apr 2011 - No ringback even though progressinband=yes is set

Any ideas on why callers who call into my customer's SIP trunk are not
hearing a ringback tone? I had this on one other asterisk system, and wound up
needing to set progressinband=yes in the SIP trunk config.

I have set this on the current system & restarted asterisk, but to no avail.

I am using:

AsteriskNOW distro
Asterisk build is 1.6 from AsteriskNOW repository:
asterisk16-1.6.2.17.2-1_centos5
FreePBX 2.9

Any help would be greatly appreciated! :-)

In my personal experience with SIP and 1.6.x, that mostly depends on
where you are sending the call to. It depends on whether the next or
subsequent leg tries to use early-audio for the ring tone, or uses a
Ringing event to signal that is what is happening. It then depends on
whether the originating caller's equipment can understand early-audio
ringing.

We have a setup here where all our trunks support early-audio ringing
except one (an ISDN30 circuit) and we have to juggle things a bit
sometimes to ensure ringing occurs.

Perhaps provide more details? Or you may find that tracing the SIP
gives you the clue that you need.

Hope that helps,
Steve

If you are referring to a ringback tone when they first dial your
system, meaning that they immediately hear your IVR when they dial your
PBX's number, it's because that's how it's supposed to work.
Unless you
tell your PBX to use the Ringing() app and wait for a period of time,
Asterisk normally picks up at the beginning of the IVR (since the first
thing you have to do to send audio via Background or Playback is issue
the command Answer() to start sending actual audio. (Note: The Ringing
app just signals RINGING to the remote party)

Steve. Thanks for the insight. I won't pretend to know what
"early-audio" is, but I guess I'm about to find out :-).

Also, I believe that I have a nearly identical setup like this with the exact
same SIP provider w/o any trouble. However, I think that system must be running
asterisk 1.4 or 1.2 (my guess is 1.4, but I'll have to check to confirm). Is
there a significant difference between 1.2/1.4 & 1.6 in this scenario?

Thanks a million!! :-)
