Forwarding to Voicemail

Hello

We have a few Cisco analog gateways with stanard analog endpoints. On our existing Alcatel system users can forward their extension anywhere including voicemail usually when they go for lunch.

This is straight forward to do with the Polycom IP handsets (just press do not disturb) but these analog handsets need to be set on the system but I can’t find a way to do it.

I have tried getting them to forward their number to *97 and *98 but when people ring their number they get taken to the voicemail system and being prompted for a mailbox number.

Can anyone recommend a way of doing this?

You could just have them put the phones in DND by dialing one of the three DND codes as appropriate
