Different voicemail box access code for MWI feature

[fernando.lagper]

I had noticed that feature, but I haven't realised that I could use it that way.

Thanks.

In the mean time, I think that for the medium-long term, at least for me and my customers, it would be desirable if "message" key would work in the way I prefer, a single key to notice incoming voice messages
and being able to check them from the very same key.

Currently, the DKP and SIP DKP phones of my PBX, and from older PBX brands we have carried all behave in the same way, so this would be consistent and comfortable for new customers.

Thanks again.
