You need to set more redirecting information [1].

In sip.conf send_diversion=yes needs to be in effect.  You also need to
setup
the from party id information (at least the from number) to indicate where
you
are redirecting from.  You should also increment the redirecting count.

chan_pjsip has the same requirements.  pjsip.conf send_diversion=yes needs
to
be in effect and you also need to setup the from party id information.

Both orderings of Ringing and Progress are valid.  It is up to the calling
device to handle it.  As you have seen, there is quite a difference in
how devices handle it.  I have even seen where the calling device needs
Ringing before Progress to handle the call correctly.  I think that case was
because the device was converting ISDN to SIP.  I do think that the devices
that don't stop local ringback in favor of the incoming RTP stream following
the 183 are broken.  Unfortunately it is something that is out of your
control.

[asterisk-users] How to correctly set REDIRECTING to indicate diversion reason

[Benoit Panizzon]

Hello List

Next question where google did not spit out an unsable answer.

When redirecting a call with Transfer, I would like to correctly
indicate the reason.

I did try this:

exten => XX,1,NoOp(Call to ${EXTEN} from ${CALLERID(all)})
exten => XX,n,Dial(SIP/ZZ)
exten => XX,n,set(REDIRECTING(reason)=cfb)
exten => XX,n,Transfer(SIP/YY)

I did try with 'reason' 'orig-reason' I added cfb with and only quotes,
I did try cfnr.

But the 302 message generated this way allways contains reason=unknown
in the diversion header.

Any hint welcome.

[asterisk-users] Ringing (180) no SDP to progress(183) with SDP transition => no audio.

[Benoit Panizzon]

Dear List

I am testing various early audio scenarios with different voice IC's,
phones and pbxes.

In Switzerland, when you operate a value added number, you have to
announce the price of the call, usually in early audio, before the call
is established.

In 'dialplan' terms this would be:

exten => XX,1,Ringing
exten => XX,n,Wait(15)   
exten => XX,n,Progress
exten => XX,n,Playback(price-announce,noanswer)
exten => XX,n,Wait(5)
exten => XX,n,Answer 

I see the asterisk playing the early announcement audio in the rtp
stream. Some devices (arris EMTA) calling the asterisk also do play it
to the caller.

But!

Most other devices I have tested just keep playing the locally generated
ringtone despite getting an 183 with SDP and the announcement is never
to be heard by the caller.

If I do to force inband ringback tone, this works with all devices I
have tested so far.

exten => XX,1,Progress
exten => XX,n,Ringing
exten => XX,n,Wait(15)   
exten => XX,n,Playback(price-announce,noanswer)
exten => XX,n,Wait(5)
exten => XX,n,Answer

Is anything wrong with the transition of ringing without SDP (to have
the local device generating ringback tone) and then start sending early
audio with 183?

[asterisk-users] How to supervise a Voicemail box with a BLF button ? What does "State:Unavailable" exactly means ?

[Olivier]

Hello,

I'm trying to supervise an existing Voicemail box with a BLF button on
Debian's asterisk 13.14.1 system.

I mostly found this [1] document.
I added in a context a line like:
exten = *7000,hint,MWI:31@default

With "core show hints", I can read this:
*7000@subs  : MWI:31@defaultState:Unavailable
Presence:not_set Watchers  1

My questions are:

1. Is this "exten = *7000,hint,MWI:31@default" statement correct ?
2. What does "State:Unavailable" exactly means ? To it means "Asterisk is
unable to find any MWI:31@default state".
3. Which Asterisk version introduced this MWI/BLF/hint feature ? Was it
supported in 1.6, for instance ?


Best regards
