Summary:                    No call progress ringback sent to PSTN caller  when
Answer() is used in context
Description: 
I notice what appears to be  serious Bug in asterisk 1.6.2.0-beta2  and 
1.6.2.0-beta4 I have searched but reports and could not find this issue
posted before. 

When I receive calls from any DID provider there is no ringback that a
caller hears  if I use Answer() in my context-dialplan

Example I have a DID 812-952-5702 from vitelity and using trunk
“vitel-inbound”
Its routed to my context “DID” which uses Answer(). When a caller
calls from PSTN to 812-952-5702 the softphone or ATA will begin ringing but
the PSTN-caller will not hear any ringtones-ringback. This issue did not
exist in earlier versions of asterisk.

My set up is very simple. I have also tested this on a fresh install of
1.6.2.0-beta4 on linux centos 5.3 server which never had asterisk before
and got the same no results.  The only way I can get caller to hear  a
ring-back tone is by removing “exten => _X.,1,Answer()”  

This issue is very serious because I need to play a voice prompt before
routing the caller to client on softphone or ata so I must answer the call
to play the voice prompt.

I even tried to make an extra Context like below.  The  first will answer
and play file than use  “Dial(LOCAL” command to call the second Context
which will not  us the answer() command  before sending the call out to the
Softphone or ATA. I even changed the r to R  and even removed the r. I done
this in every combination possible between the 2 context and still same
results.

IF I need to provide Additional  CLI outputs give me the verbose or debug
Level I need to use or any other command to output Additional CLI 


[DID]
exten => _X.,1,Answer()
exten => _X.,2,Playback(hello-world)
exten => _X.,3,Dial(LOCAL/${EXTEN}@Test123,60,Lr(9000000))
exten => _X.,4,Hangup


[Test123]
exten => _X.,1,Dial(SIP/${EXTEN}@8129525702,60,Lr(9000000))
exten => _X.,2,Hangup







Below is how my original trunk and Context settings.

Can you try not using Answer() at all, and just use Playback? Try this:


exten => _X.,1,Playback(silence/1&hello-world)

This will answer the line for you.
