Missed DTMF -is it the ATA

[mortalpert]

My IVR system fails to capture one or more DTMF when 10 digit numbers are entered, probably 7 out of 10 times.  Hookup is Cable modem to SPA2102 to Dialogic board and Teleflow software.  Software support says software OK, VOIP provider says it must be the board.  I have no dialogic support.  Is there something I can do to adjust the SPA2102

It's a slow process as I have to go through the provider.

We use G.711. They have boosted FXS from -3 to -2. How far can they

go? In the passed when I boosted the dialogic board, I've had digits

repeated.
