SPA112 Outbound DTMF Problem

[sroylance2]

I am having trouble getting the SPA112 to recognize DTMF tones from my phone in AVT mode. Using InBand mode DTMF works for the most part, but there are some IVRs that don't seem to like the audio DTMF either. Currently my phone plays DTMF tones for 80 ms, increasing that value to 120 ms resolves the issue that I am having, but I don't have time to make that change and I'm hoping to find an ATA configuration fix to my problem. I have tried several other ATAs, none of which seem to have any problem with the DTMF tones at 80 ms. Why is the SPA112 different, are there any other settings I can tweak to make this work?

You can change the default setting of Strict for DTMF Tx Mode, change it to Normal.

Located in the Line 1 under Audio Configuration.

Updating firmware to 1.3.1  or higher will fix DTMF issues,

I updated firmware and now I can dial tones even from wireless phones. Use auto mode

Solved!!
