Thanks Andrew. This is true, we do have false DTMF detections/playback 
(Lowering RX gain really helps on this). However this does not seem to 
be related. The only way to get to the IVR is through the 's' extension 
on the context in which the SPA is registered. The SPA has a built-in 
dialplan that is set to something like "(S0<:s>)". Asterisk context 
shows is the following:

[sip_pstn_linksys]
exten => s,1,NoOp(Caller-ID-number: ${CALLERID(number)})
exten => s,n,NoOp(Caller-ID-name:   ${CALLERID(number)})
exten => s,n,Set(CALLERID(name)="Externa SPA PSTN")
exten => s,n,GotoIf($["${CALLERID(num)}" = "pstn1"]?private,1)
exten => s,n,Goto(menu,s,1)

exten => private,1,Set(CALLERID(number)="Privado")
exten => private,n,Goto(menu,s,1)
