Strange thing happen with dialplan

pnirru · October 25, 2021, 7:34pm

I have a ISDN phone connect to a Digium b410p card.
Is working fine but there are some strange thing with the dialplan, with this simple dialplan


    [from-dahdi]
    exten => 1796522,1,Dial(DAHDI/g12/${EXTEN})
    exten => 1796522,2,Hangup()
    
    exten => s,1,Wait(10)
    exten => s,2,Answer
    exten => s,3,Dial(DAHDI/g12/${EXTEN})
    
    [local]
    ;
    ; Master context for local, toll-free, and iaxtel calls only
    ;
    include => default
    include => from-dahdi
    
    exten => 600,1,Playback(demo-echotest) ; Let them know what’s going on
    exten => 600,2,Echo ; Do the echo test
    exten => 600,3,Playback(demo-echodone) ; Let them know it’s over

When I call the 600, i have to answer by my own phone(i call 600 but my phone said there is a call from my own number 1796522!) and if I answer I hear the music.

If I remove the line exten => s,3,Dial(DAHDI/g12/${EXTEN}) the call give a timeout
What I miss?

Show us a call trace

I don’t know how to make a trace call, with pri debug is ok?
This is with pri debug enabled

Using this configuration


exten => s,1,Wait(1)                    ; Wait a second, just for fun
exten => s,n,Answer()                   ; Answer the line
exten => s,n,Set(TIMEOUT(digit)=5)      ; Set Digit Timeout to 5 seconds
exten => s,n,Set(TIMEOUT(response)=10)  ; Set Response Timeout to 10 seconds
exten => s,n(restart),BackGround(demo-congrats) ; Play a congratulatory message
exten => s,n(instruct),BackGround(demo-instruct)        ; Play some instructions
exten => s,n,WaitExten()                ; Wait for an extension to be dialed.
exten => 2,1,BackGround(demo-moreinfo)  ; Give some more information.
exten => 2,n,Goto(s,instruct)
exten => 3,1,Set(CHANNEL(language)=fr)          ; Set language to french
exten => 3,n,Goto(s,restart)            ; Start with the congratulations
exten => 1000,1,Goto(default,s,1)

seems to work, but I cannot still reach the 600 extension

For some reason, your priority 3 for the s extension doesn’t exist. You might want to run dialplan show and also look for non-printing characters.

Now I’m tryng this dialplan

[default]

; Wait 15 seconds for an answer (pick up the local phone)
exten => s,1,Wait(10)
; Answer the phone
exten => s,2,Answer
; They must respond within 10 seconds
; else jump to priority t (terminate call)
exten => s,4,DigitTimeout(3)
exten => s,5,ResponseTimeout(10)
exten => t,2,Hangup

[from-dahdi]
exten => 1796522,1,Dial(DAHDI/g12/${EXTEN})
exten => 1796522,2,Hangup()

[local]
;
; Master context for local, toll-free, and iaxtel calls only
;
include => default
include => from-dahdi

exten => 600,1,Playback(demo-echotest) ; Let them know what’s going on
exten => 600,2,Echo ; Do the echo test
exten => 600,3,Playback(demo-echodone) ; Let them know it’s over

What did you think of this?

[from-dahdi]
include => local
exten => 1796522,1,Dial(DAHDI/g12/${EXTEN})
exten => 1796522,2,Hangup()

exten => s,1,Answer()
exten => s,2,Wait(1)
exten => s,3,Dial(${CONTEXT}/${EXTEN})
exten => s,3,Hangup()

[local]
include => default
include => from-dahdi

exten => 600,1,Playback(demo-echotest) ; Let them know what’s going on
exten => 600,2,Echo ; Do the echo test
exten => 600,3,Playback(demo-echodone) ; Let them know it’s over

That definitely doesn’t have a priority 3, so will never get past the Answer.

pnirru · October 27, 2021, 8:26pm

Finally I have solved the first 50% of problem

Reading from this howto https://bach-online.de/make-internet-calls-with-a-real-isdn-phone/ i modify my /etc/asterisk/chan_dahdi.conf adding/modify those lines.


overlapdial=yes
immediate=no

Now from the isdn phone I can call the sip phone and finally the internal extensions answer, this is the extensions.conf

[from-dahdi]
include => local
exten => 1796522,1,Dial(DAHDI/g12/${EXTEN})
exten => 1796522,2,Hangup()

exten => s,1,Answer()
exten => s,2,Dial(Local/${EXTEN},10,t,m)
exten => s,4,Hangup()

[local]
include => from-dahdi

exten => 1001,1,Dial(SIP/telefono1,20,Ttm)
same  => n,Hangup

exten => 7500,1,VoicemailMain(@mycontext)

exten => 600,1,Answer()
exten => 600,2,Playback(demo-echotest) ; Let them know what
exten => 600,3,Echo()                  ; Do the echo test
exten => 600,4,Playback(demo-echodone) ; Let them know it
exten => 600,5,Hangup()

I still have the problem of the isdn-ta adapter (can receive the answer, but cannot call)
but problably is hw problem, hw misconfigured, os misconfigured, but at least I have solved the dialplan problem, thanks for help
