I have (I guess) a v1.0 Grandstream 4104 gateway. I have the latest firmware for it, yet the caller ID is only 50-50 (sometimes I get nothing). As others have complained about this, I assume it is just a Grandstream issue. The other items supported according to the 3CX page are a Patton 4114 and the Sangoma card. Are there any other tested FXO gateways people here have used? I'd sort of like to keep to an Ethernet (external, not a card) solution, if possible. But I have tried the Grandstream, and the only other choice is the Patton. So looking for more options.
