I made the mistake of purchasing a Gigaset C530 IP (plus 3 additional handsets) to replace an aging analog DECT phone. $250 later, I’ve come to the conclusion that this thing is utter garbage.
So … is there a VoIP/DECT system out there that comes at a reasonable cost and supports these features:
- Off-hook dialing - I.e. the off-hook button on a handset and have it immediately connect to Asterisk (where I’ve implemented a dialing “decision tree” with the DISA application)
- Message waiting indicator that works with Asterisk voicemail (as far as I can tell the C530 IP simply doesn’t have a MWI, even though its documentation claims that it does)
- Backlit buttons
- Speakerphone function
- No/configurable “busy tone” when the other party terminates a call
- Decent physical feel (something that doesn’t feel cheap/small)
Honestly, I wouldn’t think that it would be difficult to find a reasonably priced VoIP/DECT system that has these features, but I’ve always been naïve.
