Anyone know if an ata exists that you can whitelist numbers? Prefer not to do on pbx side and have ata connect directly to Sip provider. Looking to setup for an elderly person and only allow specific people to call.
Such a setup is easily achieved but has nothing to do with what the call terminates on be it a VoIP set or an ATA pretending to be a VoIP set. I seen carriers that provide an IVR to allow the customers to add numbers to a blacklist and the vertical service code to access and use that could be accessed from any set (including an ATA).
I’m using Ooma device connected to a regular phone. The service offers a few levels of call filtering. I have a contact list I throw at it every so often and set the filter to only allow calls from people I know. Everyone else has to leave voicemail.
Your post was removed from r/VoIP for violating Rule 1: No promotion or advertising of any kind.
Recommendations, advertisements and promotion of any business, product or service is only allowed in response to requests in the monthly requests thread.
Promotion, advertisement or recommendation of any kind outside of the requests thread is strictly forbidden.
So the device allows you to add white/blacklists with no connection to the service provider? You can access it on your local network and make the necessary changes at any time?
That’s done on the LO/HO, PBX, or CENTREX
