Re: [Linphone-users] DTMF not working any more on iPhone?

Hi Simon,

I updated to 1.0.5 this morning.  In the meantime, it sometimes worked, sometimes not.  This afternoon, with 1.0.5, it did not.  I always use the same VOIP server (provided by Free, my ADSL provider), so it's probably not the reason of the issue.  

But my ADSL traffic is not so good these days, and some people complained to me about the quality of the sound.  Maybe it's just that...

Thanks for the answer.

As a consequence the reliability of DTMF transmission depends on the
server support for telephone-event encoding, and in other case on the
choice of the codec and the quality of the network layer (with packet
losses, dtmfs can be splitted in two or erased...).
