[asterisk-r2] Problem DTMF R2 Cellular Networks

[martin rodriguez]

Hi:

I  have any problem with DTMF over R2 from cellular networks. Does not
recognize the DTMF when I press the keys. I have the dtmfrelay
activated. When calling from a cellular service does not work in
correctly, but from fixed operator (isdn, r2, analog lines, sip
providers, etc.) works

someone, I'll present the same problem using unicall? I'm from
Argentina (Cellular Company Claro - Movistar - Personal).

Versions:

libmfcr2-0.0.3
libsupertone-0.0.2
libunicall-0.0.3
zaptel-1.2.22
asterisk-1.2.20

Bye
