Hi all, we are about to install a 3CX at a client using SIP trunk from Maxcom in Mexico. The trunk provided uses IP base authentication and it currently working with and old snomONE IP PBX. All these inside the premises of the client. On our initial tests, we have modified the firewall rules to open the 3CX ports but when we change the NAT rules to pint to the new 3CX install we can not make or receive calls. We tried the Uk Gamma trunk as an example also of and IP based trunk but not working either. Anyone has experience with Maxcom in Mexico or similar trunks?
Thanks all!
Nathan
