Thanks for the suggestion! I have tuned the SIPURA SPA 2000 gain as suggested and also re-adjusted X100P gain and echo cancel. That helped a lot with audio quality. But still cannot send DTMF tones out over PSTN. As well I discovered DTMF transmission from IAX soft phone out to PSTN is not at all reliable either, so it seems to be on the PSTN (X100P) side somewhere.
I cannot find any settings to tweak DTMF transmission other than relaxdtmf, and can't find any log messages which indicate anything is going wrong. A plain analog phone plugged into the PSTN sends DTMF which is recognized ok.
