Re: SPA400 and SPA9000 system. cannot use tone with automated ph
I assume you have no issues with the IP phones sending DTMF digits to the same automated system. If it is only related to ths FXS port, this looks like a DTMF level issue. I would suggest you check the [FXS] settings, more detailed, the DTMF Tx Method:and set it to InBand. Then, go to [Regional] Settings, and set DTMF Playback Level:to a larger value, lets say -13. This should solve the issue.
If not, I would suggest you open a case with the support center to perform live troubleshooting.
