I expected that when a call is in progress, I could use the keypad to send tones to my (Australian) ISP, or to '[phone]' (VOIP test call). This worked with Linphone as supplied with Ubuntu 13.10.

It does not work with 14.04. Setting 'use_rfc2833=1' in .linphonerc doesn't fix the problem, whether or not use_info is set to 0 or 1.

Status changed to 'Confirmed' because the bug affects multiple users.

After upgrading Ubuntu from 13.10 to 14.04 LTS I can now no longer send DTMF tones to my PBX. This used to work in the previous version of Ubuntu.

My PBX specifies RFC2833 as the only way to send DTMF signals, and Linphone is useless to me without it.

Any estimate of when this might be fixed?

Anyone working on this??

it seems that it still does not work even with the latest linphone 3.7 upgrade for ubuntu 14.04

It's been almost a year, and still no fix in place. What happened to "LTS"?

[Graham Jenkins (grahjenk)]

Any update on this? Perhaps 3.8.1 works?

[Graham Jenkins (grahjenk)]

And the version installed on Ubuntu 15.04 (3.6.1-2.4build1 amd64) has the same issue!

3.8.1 ?
