I've tried automatic call forwarding on a SPA-232D. Unfortunately it does not work. Whatever I try, there's always a voice, that the number is not valid (if I call the number on where I have set up the call forwarding). I'm starting to doubt whether call forwarding on a DECT Line to an external phone number is possible (?).
- Firmware: 1.4.1
- Portforwarding on: DECT Line x
- All Supplementary Service Subscription options are yes (except Service Announcement Serv)
Port forwarding on an external mobile number:
- Cfwd All Dest: 41998887766 (41 for Switzerland, What's the syntax in general? are there any "-")
What needs to be considered? I appreciate any help!
