asterisk users - Sep 2016 - Multiple phones when one is unregistered

I have an extension that looks like this:

exten => 5555551111,1,Verbose(Door buzzer calling)
  same => n,Dial(SIP/user1&SIP/user2&SIP/user3)

The idea is that any of the three users can answer the phone to let
someone in.  The problem is that if, say, user2 unplugs his phone then
the call immediately goes to his voice mail and the other two do not
have the ability to open the door.

Is there any way to direct only to phones in a list that are currently
registered?  I am sure that I can write a rather convoluted extension
to check for registrations and create a dial command but I am hoping
that there is an easier way so that I can create these types of
extensions for other clients easily as well as being able to add and
remove destinations quickly.

Cheers.

To my opinion, you need a queue with dynamic agents. 

SIP/userX subscribes and checkouts manually, or better SIP/userX adds to 
the specific queue at the moment she or he registers to the system. I know 
how to do the former, but I would like to know about the latter. If someone 
could comment on that, I would highly appreciate.

The Asterisk behavior is such that even if one of those users are 
unregistered the other two will continue to be called. Is something 
upstream from Asterisk doing the voicemail?

The dialplan below cannot go to voicemail, either something else is 
going on or the dialplan below is not the actual dialplan. Calls only go 
to voicemail when the dialplan runs the VoiceMail application.

Paste the Asterisk console output of a call showing the problem, maybe 
someone can help.

There is nothing in that dialplan snippet you provided that would send 
anything to voicemail.  In fact, if you used that snippet, it would give the 
exact behaviour you describe yourself as wanting!

Here's a protip for you:  It's *not* a massive corporate secret, which
phone
will ring when somebody dials what number.  Obfuscating your real dialplan 
like that just makes it harder for other people to help you.

Of course not.  It's the individual extensions that have voice mail.  I
have a similar problem when one of those destinations is a cell phone
but I know that there is no Asterisk solution for that problem.  If the
cell phone answers and goes into the cell phone voice mail I am
screwed.  I can't fix that unless I also run the cell phone company.

In this case the extensions are all set up in the same asterisk
server.  Here is an example.

[user1](client-phone) 
secret=NotTheRealSecret
callerid=John Doe <5555551212>  
mailbox=user1 at VoiceMail
context=pbxout-19212

And here is the extension that calls it.  Sorry about the wrapping.

user1,1,Verbose(0,Entering extension user1)  
 same => n,GotoIf($["${DEVICE_STATE(SIP/9999906549)}"
"UNAVAILABLE"]?DialCell)
 same => n(DialWifi),Verbose(0, ${CALLERID(all)} Calling ${EXTEN} and
SoftPhone)
 same => n,Dial(SIP/user1&SIP/9999906549,30)  
 same => n,Goto(VoiceMail) 

 same => n(DialCell),GotoIf($["x7165550000" =
"x"]?DialDesk)
 same => n,GotoIf($["${CALLERID(ani)}" =
"7165550000"]?DialDesk)
 same => n,Verbose(0,${CALLERID(all)} Calling "${EXTEN}" and cell
 "7165550000") 
 same => n,Dial(SIP/user1&SIP/thinktel/7165550000,30)  
 same => n,Goto(VoiceMail) 
  
 same => n(DialDesk),Verbose(0,${CALLERID(all)} Calling ${EXTEN}) 
 same => n,Dial(SIP/user1,30)  
  
 same => n(VoiceMail),Set(CDR(userfield)=VoiceMail) 
 same => n,Set(_ACCOUNT=user1)  
 same => n,VoiceMail(user1 at VoiceMail,u)  
 same => n,Hangup() 

It's a complicated extension but I believe that the following is the
essential part.

user1,1,Verbose(0,Entering extension user1)  
 same => n,Dial(SIP/user1,30)
 same => n,VoiceMail(user1 at VoiceMail,u)
 same => n,Hangup()

Here is what the log shows.  I can't put the unregistered user back at
the moment.  Perhaps I can do it overnight when no one is going to the
building.

[Aug 23 10:20:55] WARNING[-1][C-0001fee7] app_dial.c: Unable to create
channel of type 'SIP' (cause 20 - Subscriber absent)

I am assuming that the voice mail is for the absent (unregistered) user.

Other than sanitizing the buzzer phone number and the user names this
is the full extension for the buzzer.

All I did was sanitize the buzzer phone number and the names of the
users.  Other than that the above is the complete dialplan.  See my
other message for details of those extensions.  I didn't think that
there was anything relevant in that but I could be wrong.

Something like

exten => 5555551111,1,Verbose(Door buzzer calling)
same => n,Set(toRing=)
same => n,ExecIf($["${DEVICE_STATE(SIP/user1)}" = "NOT IN 
USE"]?Set(toRing=${toRing}&SIP/user1)
same => n,ExecIf($["${DEVICE_STATE(SIP/user2)}" = "NOT IN 
USE"]?Set(toRing=${toRing}&SIP/user2)
same => n,ExecIf($["${DEVICE_STATE(SIP/user3)}" = "NOT IN 
USE"]?Set(toRing=${toRing}&SIP/user3)
same => n,Dial(${toRing:1}) ;to remove the first &

would do the work

That looks good and is easy to add and delete from the list.  I will
give this a try one night this week.  Not sure what that last line
would do if all of the phones are off but if they are the buzzer won't
be answered anyway.

Thanks.

Failed.  I checked the online docs and the syntax seems to be correct
but I get this:

[Aug 31 21:52:00] WARNING[-1][C-0001fed5] pbx.c: No application
'ExecIf' for extension (unauthenticated, 5555551111, 3)

Is there a module that I need to load?

In case it matters I am running Asterisk 11.23.0 on NetBSD 7.0.

Set is a function, not an application. ExecIF executes an application.
I'm a bit confused by this whole topic. The dialplan snippet in the 
original email
> exten => 5555551111,1,Verbose(Door buzzer calling)
>    same => n,Dial(SIP/user1&SIP/user2&SIP/user3)
should have rung the phones forever as long as one phone was active and 
not forwarding or DNDing.

I wondered about that but the docs are not very explicit on the subject
and I thought that the other poster was suggesting something that he
had used/tested.

So does the Dial command go directly to the registered device or does
it use the extension?  I was assuming that it was going to the
extension's voice mail if it wasn't there but that's in the
extension
dialplan and I suspect that the extension is irrelevant and only the
SIP registration matters.  That would be a good thing since many
extensions also ring the user's cell phone and that would be annoying
if they were at home when someone came to the office door.

Perhaps my problem was that one of the users was removed from sip.conf
but their phone was still in the above plan.  For example, user2 leaves
the company, is removed from sip.conf but we forgot to remove him from
the door buzzer extension.  That might give me the behaviour that I was
seeing.

I think I have enough information now to analyze this problem if it
happens again.  Thanks for the help.

Yes, that's why you provide the technology part (SIP/, IAX/,
DAHDI/)

If the target device has a forward configured, I believe Asterisk will 
dutifully ring the forward number like it was told, but could be wrong.

Otherwise, it'll only go to voicemail, in asterisk, if you tell it to in 
the dialplan. Could it be going to voicemail on a forward somewhere?

In my experience, that too should not be a problem. I've got the same 
dial command structure, ringing multiple SIP/extensions in one dial 
command. I have some instances where the SIP entry in sip.conf no longer 
exists, and some instances where the device is not registered, and 
asterisk just displays a warning and continues on.

I don't think so. At least I don't see that.
