Help configuring Grandstream ATA GXW4248 with 3CX


Looking for someone to help walk us through an onboarding of a client that has GXP2170 phones on ATA model GXW4248. This will need to be configured with 3CX. Do you usually outsource for assistance or does Grandstream offer support for configuration?


You don’t need a 4248 if you have 2170 handsets. The 4248 is an FXS gateway and the 2170’s are SIP handsets.
