Hi,
I have a A400P card with two FXO and one FXS modules. I'm running Elastix and everything looks ok except that when I send DTMF tones from an analogue phone to FXS module the tones quality both in sip phones and the called PSTN phone number (Analogue Telephone->FXS ->Asterisk->FXO->PSTN->FarEnd PBX->IVR) is very bad and the remote IVR (DIGITAL RECEPTIONIST) makes wrong selection.
Any help please?
Thanks in advance,
Dimos
