[jitsi-users] DTMF tones distortion?


#1

Hey Mark,

Please note that the mailing list address has changed.

You may want to try the latest nightly. You could also try switching DTMF
methods and checking if any of the others work better. (Generally SIP INFO
and RTP are more reliable than wideband).

Hi, when dialling into a hosted teleconference, where a participant is

systems don’t properly recognise the DTMF tones generated by jitsi. Even
through my headset (assuming that is representative of what is sent down
the line), the tones sound clipped and slightly distorted to me; I think an
earlier version of jitsi worked better in this respect.****

Using the same PC and the same teleconference call, I made test calls with
two other softphone applications which consistently registered the codes
fine, so it’s not my PC or the connection. With jitsi, I got past the
joining code successfully just twice in about 10 attempts.****

Anyone else seen this problem? And is it possible to ‘clean up’ the tones
for jitsi please?****

Hi,

         I reported same problem some time back, I have even sent network traffic dumps but problem still remains.

         I have to add some small improvement, In latest 2.3 builds DTMFs now work with PortAudio (had to disabled telephone-event codec), but unfortunately PortAudio has another issue, input sound (from Mic) has a very big delay (tried in Fedora 18).

     So a fix of DTMF tones when using PulseAudio would be great.

     Regards,

         Adelino.

Thanks Emil.

I was already trying a recent nightly build, but initial testing suggests that setting DTMF Method to SIP INFO is working much more reliably than my previous setting of AUTO (RTP/inband, no SIP_INFO).

I have also told a couple more users with me who were having the same problem, and hopefully they can confirm it works for all of us.

Thanks for your help.

Mark (and new mailing list noted for future)
