Hi Is this possible, I have a setup Voxeo---Ser---GW Problem is when voxeo dials, the gateway does not support dtmf in the format that voxeo wants it, when the call from voxeo is to a IP phone dtmf works fine. I also have asterisk --ser---gw, now when someone dial from pstn to asterisk, asterisk understand sthe dtmf just fine, so in order to overcome the problem could I do Voxeo--ser---asterisk---gw, and then if someone comes via pstn, asterisk will recongnise the dtmf, and it could alter and send to voxeo...is this possible Iqbal
