You have my deepest sympathies regarding care for a dementia sufferer .
It may be worth getting a solicitor involved and offering up the usual threats that if they cannot provide a solution then you will hold them responsible for any costs and legal costs which arise.Chrisn wrote: ↑Tue Jul 31, 2018 8:17 pmThanks for the feedback, unfortunately after a long chat with a person at BT I discovered that 0871 numbers dont count as premium rate so BTs premium rate blocking option wouldn't work, also some exchanges can't support all of the call blocking options , and you guessed it, mums exchange is one of those.
The OBi models I mentioned above are much improved descendants of the Cisco devices; some of the same engineers who designed the original Sipura devices also designed the OBs. (Sipura was acquired by Linksys. Linksys was acquired by Cisco. Cisco eventually sold Linksys and that VoIP adaptor product line was acquired by Belkin. Other than changing the case and labelling there has been no development on those Sipura/Linksys/Cisco/Belkin units for more than 10 years. They are all the same inside.) I have 2 Linksys and 3 Obis. The OBis have much more extensive facilities and the OBi110 or OBi212 will single-handedly do what the OP requires. No Asterisk, RPi or any other computer required other than a web browser for configuration. The Sipura/Linksys/Cisco/Belkin units or the Grandstreams do not have the functionality to provide a single box solution.vinnieb wrote: ↑Wed Aug 01, 2018 8:39 amThis is the same option as going down the exclusive VoIP option, just 2 different ways I've played with it here..
There's free phone exchange software out there that would run on the pi, called asterisk. There's distros made just for the pi with everything pre installed. That's VoIP based, so the next bit is how to switch your phones to VoIP..
Cisco so a converter, spa112 for about 40 quid. That will let you plug in a normal landline style phone, and a normal landline connection, and convert them to VoIP compatible devices on your Ethernet network.
You then register this is asterisk, and setup some call handling rules. I think with pattern matching, you could match on a specific number, or number starting with a premium code, and block, play a recorded message, or redirect the call to yourself, whatever might work best.
Unfortunately, none of that is super easy, though there are alot of guides available that would take you through it. I've put that setup in place a couple of times as an amateur, and it was a good few days to get it working. Maybe some IT company could do it for a price, but it could be considered a business like setup and may cost a bit.
Potentially you could simplify it though, I've taken the spa112 out of the equation here, and bought handsets that can do VoIP and normal landline. And subscribed to a good VoIP line provider (about a tenner a month). That way you'd just need to setup asterisk on the pi, register your VoIP line and the handsets register to asterisk. One less bit of kit to configure. The VoIP provider I use has quite a lot of extra config available, so some may offer the functionality of redirecting numbers in their own GUI/system.
Hope that helps
