Does the phone support redialling the lasst number?
What about quick-dials? The manual of the 60s-mobile phone says it's supported but no mention in 60s-cable manual...

The Opis 60s cable supports redialling. The last number dialled can simply be repeated by taking the receiver off the hook and then dialling R/# (for repeat).

We are sorry but quick-dials are only supported by the Opis 60s mobile.
