We are running the Pro version of 3cx in multi company mode to provide hosted services for our customers. I understand that SIP ALG needs to be disabled on the network running the PBX, but what about the tenants network? If we are unable to disable SIP ALG will this pose a problem with 1 way audio as well? There are a lot of networks we dont have any access or control over, and we want to make sure if we install the system for them, it wont cause issues.
