Hi,

I have a problem with my PBX. If I call outside, and if a virtual receptionist ask for pressing buttons, buttons are not detected.

Any idea?

thanx

I would investigate how the DTMF is sent on your outbound trunk.
Are you using IAX or SIP. is the dtmf option specified in your trunk configuration?

yes you can try to setting the dtmfmode=rfc2833 or auto else inband or info into your trunk.
But rfc2833 normally will be good

It's not danardarf, but danardf.
Or simply : Franck ;)


So...
Into your trunk parameters:
host=.....
username=.....
secret=****
dtmfmode=inband or
dtmfmode=auto or another
dtmfmode=rfc2833

Here is mISDN.conf:

;[intern]
; define your ports, e.g. 1,2 (depends on mISDN-driver loading order)
;ports=1,2
; context where to go to when incoming Call on one of the above ports
;context=Intern

;[internPP]
;
; adding the postfix 'ptp' to a port number is obsolete now, chan_misdn
; parses /etc/misdn-init.conf and sets the ptp mode to the corresponding
; configs. For backwards compatibility you can still set ptp here.
;
;ports=3

;[first_extern]
; again port defs
;ports=4
; again a context for incoming calls
;context=Extern1
; msns for te ports, listen on those numbers on the above ports, and
; indicate the incoming calls to asterisk
; here you can give a comma separated list or simply an '*' for
; any msn.
;msns=*

; here an example with given msns
;[second_extern]
;ports=5
;context=Extern2
;callerid=15
;msns=102,144,101,104

[misdnchannels]
ports=1
msns=*
context=from-pstn
echocancel=yes

I don't know mISDN.conf. :huh:
But if you put your language information into this file, it's should be good. I think a format adaptation in relation to language.
Or maybe set dtmfmode=rfc2833 into sip.conf [general]

I've solved my issue setting dtmfmode=info. The remote IVR works ok, but I've rode somewhere there are problems with teh inbound calls with our IVR.

You have put this parameter into the sip.conf file?

Hi there, I had the same problem but i fixed it by editing my trunks and adding (or editing) the dtmfmode line as follows:

dtmfmode=rfc2833&info&inband

It solved my problem, hope it solves yours.

[ADDED TEXT]

I see you solved your problems but let me tell you that the DTMF most used standard worldwide is rfc2833 so I strongly recommend you NOT to leave it out of your trunks configurations. I still recommend you to use my settings for it will will cover all possible standards of external dialpads.

Good day,

I recently installed a Digium B410P card on Elastix 5.2 and for some users on inbound calls it is not recognising the pressed IVR choices. This will eventually lead to a timeout t being excuted instead.

The card is configured to use mISDN drivers. Where do you change the dtmfmode with misdn??
