First, thanks for your reply.
Do you have the CxDtmf.pdf document, from Eicon ?

If I understand good, you have to enable DTMF facilities 248, 249 and 250,
and then you receive DTMF code for tone detection :
0x81 for unidentified ton detected
0x80 for end of signal detected
0xC9 for human speech detected
Etc...

So, with DTMF code, you could handle it like for fax : redirect to extension
"vad" or something ...
