Hi, Our two vendors informed us that Adtran will no longer be selling Adtran Ip 712 phones; some time back I heard they were no longer manufacturing Netvanta 7100 boxes and I just realized that there has been no new firmware since 2017 where before they used to have several firmware updates in one year. So is it over? Should I be looking for another solution to replace our PBX systems? Appreciate the input. Thanks.
I would recommend finding a new option. Adtran states that they will continue to support the product until Dec 31, 2020. The last shipment date and end of software date have already passed.
