Problem with rotary phone

Asterisk Asterisk Hardware
1

Debian 11, latest asterisk from Debian repository.
I have connected to a TDM400P an old rotary Phone.
The problem: I want to dial 600


; Test dell'eco
exten => 600,1,NoOp()
same => n,Set(CDR(mycustomfield)=coffee)
same => n,Verbose(I need some more ${CDR(mycustomfield)})
same => n(open),Answer()
same => n,Playback(demo-echotest) ; Let them know what
same => n,Echo()                  ; Do the echo test
same => n,Playback(demo-echodone) ; Let them know it
same => n(close),Playback(go-away2) ; Let them know it
same => n,Hangup()

But after instead of “compose” 600 the composing finiish at 6 or 60 and I heard free tone!

On console I see this

This is the chan_dahdi.conf

You haven’t include the included file.

You haven’t included the complete dialplan, as it appears, from the log, that 64 is valid extension in the dialplan, even if no-one is parked there. Having extensions that were variable in length really wasn’t something that was done in the era of pulse dial phones.

You might want to have a look at:

Given your numbering plan, I suspect you are being caught out by matchdigit_timeout.

When providing logs, please provide full logs, wither a verbosity of 5. Pure debug logs don’t have the necessary context.

If 64 was 60, the dial speed may be wrong.

I have tried to set the timeouts, but nothing change


firstdigit_timeout=16000
interdigit_timeout=10000
matchdigit_timeout=8000

On console I see

Now when I compose 600

sometimes after 6 “close” sic!
sometimes after 60

and return the line free tone!

Testing the rotary phone on my telco-router, and works perfect

You need the full log, which has the debug, warning, and verbose lines in the correct relationship to each other.

As noted, 60, not 64 was seen.

You appear to have a pattern in your dialplan that is matching 6X, not just one for 600.

I have try a very simple dialplan

[from-dahdi]
exten => 1000,1,Dial(SIP/1001,10,t,m)
exten => 1000,2,Voicemail(1001@interni)
exten => 1000,3,Hangup

exten => 1006,1,Dial(dahdi/g15,10,t,m)
exten => 1006,2,Voicemail(1006@interni)
exten => 1006,3,Hangup

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

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()

Try increase the debug

core set debug 5
core set verbose 5

This is the result

Very strange, I remind when I bought the phone last year works fine without any special configuration

Sometimes another error…

I presume the card is old or second hand, as, for a supported card, the advice would be to get support through Sangoma’s commercial web site.

You seem to be getting a lot of bogus 4s. I don’t know if the pulse counts are done in hardware or software, but in the former case, the problem is in hardware. You probably need to put an oscilloscope on pair from the phone and see if the pulse timing and currents are in specification.

I assume if you are playing with rotary dial phones there is a good chance that you have test equipment or the ability to improvise it.

I have ordered a more recent card pci-e fxs.
But very strange, this card works at least the latest year…

It appears that DAHDI hasn’t supported that card for a long time! What version of DAHDI are you using?

14

Dahdi git+old sources+patch for wctdm module “rebirth”
If you want i can paste my slackbuild.

p.s=i’ve solved

15

Solution found. I put another rotary phone and…works!
So was probably some hardware problem or on other rotary phone (broken? :unamused: )
But…why the old phone works with TELCO line?

EDIT1: i found the “solution”
Was the number composed too fast!
The other rotary phone has the “circle” more slow than this, if i make the number slowly…all works.

16

Depending on the make/break ratio of the dial, that may affect your success.

You can use the Asterisk dial pulse speed test[1] to measure your dials and see what the speeds and make/break ratio are. If it reports “FAST”, then that may explain it. I typically don’t have issues with dials that are within 1 or 2 pps of the desired target range.

The linked resource also adds the wctdm driver back to DAHDI (in addition to making the dial pulse speed test possible).
