Log the actual DTMF to your console, set in logger.conf:

console => something,something,dtmf
                                ^^^^

Then try again and check if you see the actual DTMF. If you do and it 
still doesn't work, try

dtmfmode=inband

for your voipms peer.

rfc2833 has been working always unreliable for me.

Also, I'm doing DTMF like this:

exten => 5000,n,Dial(SIP/123456 at provider,,D(wwwwww1ww2ww3ww4))

Just use more w's to generate your 3 seconds pause. No need for SendDTMF.

For more debugging just call yourself on your UK mobile from a softphone 
and press digits and watch the console and listen on your mobile if you 
hear the DTMF.
