Hi, I bought a DVG 6008S VOIP Gateway with 8 FXO Ports, 4 Lan ports and 1 Wan Ports, i'm trying to use 5 PSTN Lines with the gateway using 3cx, and the problems are: 1st. The gateway can't register with 3cx 2nd. The 3cx says: -Line:10000 doesn't match provided: 6646971 vs test1 -Registration request from sip:firstname.lastname@example.org:5060 failed. Reason: Credentials don't match, check that authorization-ID and password match the ones in extension settings -REGISTER db4e97c2c663 cseq=REGISTER email@example.com:5060 / 18 from(wire) failed authentication This is the first step to config the 3cx with the Gateway. Thanks !
