Cumbersome, why not just use some custom headers (stored in usr_preferences)?
kamailio stuff:
if($avp(src_dtmfmode)!="")
{
append_hf("X-DTMFMode: $avp(src_dtmfmode)\r\n");
}
asterisk stuff:
exten => _[+X].,n,ExecIf($[${LEN(${SIP_HEADER(X-DTMFMode)})} >
0]?SIPDtmfMode(${SIP_HEADER(X-DTMFMode)}))
The other way around is bit more tricky. YOu have to dial using the M option
(i'm using AGI instead of RT):
M(setdtmftx^".$row['dtmftx'].")
[macro-setdtmftx]
exten => s,1,NoOp()
exten => s,n,SIPDtmfMode(${ARG1})
exten => s,n,MacroExit
