Hi, Just wondering anybody here who did bridging the grandstream with 3cx. It's a customer requirement and we have to go with it, they have reason for that. However, we tried to configure it by creating new SIP trunk, but the call from Gransdstream network, goes to IVR instead of going directly to the user extension. Anybody has idea what is wrong here? My aim is to from Grandstream phone, call directly to the extension inside the 3cx network. Both network are reachable and with separate dialing numbers. Thanks for the support.
