In general, Voip phone(or ATA) has an SEND-DTMF(or DTMF-Tx-Method) option,it has 3 items:

1. in audio, or Inband; in audio=Inband

2. via RTP(RFC2833), or AVT; via RTP(RFC2833)=AVT

3. via SIP INFO

via RTP(RFC2833) is the best choice.

I think Voxalot should make it clear that which DTMF transmission method to be supported by Voxalot side, otherwise most Voxcall member's SIP URI need to be activated manually by Martin or Craig.
