But I've now solved the problem!

I suddenly remembered that in one of my occasional bouts of rate
checking and updating of dialling rules (if something is cheaper from
another provider) Sipgate were some parts of a penny cheaper for 0845
calls. So I changed the dialling rule for 0845 calls to go through
Sipgate rather than JustVoip which I'd been using for 4+ years. I
experimented with a switch back to JustVoip and DTMF tones are now
recognised in menu options!

Can anyone think why Sipgate should handle DTMF tones differently to
JustVoip?
