I've asked for help (link, below).

 

I received instructions on how to enable DTMF debug detail.

 

It seems​ Linphone isn't sending DTMF.  I am aware of the in-band and out-band DTMF settings (no clue about their function) and have tried 00 01 10 11 without success.  I setup Asterisk for ulaw but also tried GSM and G722 without success.

 

I verified from another phone that DTMF debugging is on (see link, below, for details).  I see DTMF detail for other phones but not Linphone.

 

I would sincerely appreciate any pointers.

 

Thank you very much!

Hi, I am running Linphone on my Google Pixel 6. I can dial-out successfully. When I dial out I do not hear DTMF but I see the phone number displayed on the console of my Asterisk PBX. When I try to access voicemail I do not hear DTMF, I do not see digits displayed on the console, and voicemail prompts me to enter the number until it times out. If I call-in externally using an analog phone DTMF works–I don’t know if this is an applicable or valid test-case. I hear the DTMF, see the digits d...

Hi,

 

Linphone supports  DTMF using SIP INFO or RFC 4733.

 

Asterisk typically supports the same.

 

Maybe your Asterisk server is not set tup properly to perform DTMF.

 

Best regards,

Hi,

 

I've been using Linphone on Android for many years as a secondary option, which I liked.

 

I successfully dial and receive calls.

 

I am hoping to use Linphone on my Android as a primary option and, in testing, have run into a problem.

 

My droid Linphone is connected to an Asterisk PBX.

 

I just noticed DTMF does not seem to be working in some cases (as mentioned, I can dial-out).

 

When I try to access voicemail the PBX doesn't seem to respond when I enter my mailbox number.

 

When I noticed this my next test was to try DTMF on another service.  I called a customer support number and tried to use DTMF.  That didn't work, either.

 

I do not hear the tones.

 

Can anyone please offer some suggestions on how I can get this working?

 

Thank you very much!
