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.
