Posted By: jomaha Voicemail dtmf control tones & fast busy - 12/02/08 06:47 AM
I just had an old voicemail system conk out & am now routing the voicemail ports on a DK424 into fxo ports on an Asterisk system. All calls routed to vm are fowarded from stations on the dk424 and originate on other stations or enter the 424 though a T1.

Asterisk does not listen for D,A & B tones. I have turned PGM31 led 19 & 20 off, but when I turn off led 15 I am getting recordings of the fast-busy-tone (which I assume is referred to as Auto Release) When I leave 15 on, I get occational blank messages - probably due to asterisk-voicemail's silence detection being misled by the D tone.

Is there a way to make the toshiba not generate an auto-release tone and not send extra dtmf tones when the voicemail leaver ends the call (note that no calls are from loop start trunks - so no help with PGM15)?

...or best have the Toshiba's voicemail fxs port simply hangup at the end of the call?

Is D tone defined in tones.h ?

I wonder, never tried

In extension.conf add something like

exten =>D,n,Hangup()

I see your talking Asterisk. Indeed,
exten =>D,n,Hangup()
works. In fact I'm doing something similar to catch hangups before the call is bridged to the voicemail application. The problem is when the call is bridged (in asterisk) to there are 2 pointers passed to the recording function,
char *acceptdtmf = "#";
char *canceldtmf = "";

I could simply change the # to D, however this machine does much more than be a Toshiba Voicemail system so I am working on a patch to have the vm-app accept an extra option (without rewriting the whole program). This is still not going to be a perfect solution as those 2 parameters are not perfect matches to the dtmf A & D functionality.

At any rate, the best solution would be to have the toshiba hang up without sending tones of any type when the call terminates. And for the purposes of this discussion, I am regading it as a Toshiba question (I'll share the patch and voicemail contexts - but should get it working first).

Ya Toshiba will always give something, The D tone if active. If not, it will just give reorder.

Yahoo! I came up with an asterisk solution. Turn on LEDs 15,19 & 20 in PGM31 on the Toshiba. I'll post my initial setup here - but it will probably be tweaked and I'll post that at:

Anyway, by passing the audio through Asterisk's MeetMe application, it can be made to listen for any dtmf tone. This setup currently just hangs up when a 'A', 'B' or 'D' tone arrives but minor modifications (see the 'exten => _[ABD#],1,Hangup()' line) opens up the possibility of going far beyond typical voicemail integration (that is the nature of Asterisk).
Now a couple of notes:
1) Voicmail ports arriving into asterisk are all two digits. You may have to make modifications to use this. They arrive in the vm_from_toshiba context (as defined in zapata.conf).
2) All of my Toshiba extension are in the form 7XXX
3) Asterisk is extremely flexible so regard this as a rough guide.


In Zapata.conf

callerid="Voicemail HS trunks" <7000>
channel => 49-56 ; These are the two digit ports mentioned above. The digit number is important where the ${CHANNEL} variable is referenced.
