To ensure the best voice quality possible and avoid any connectivity issues, the following ports and IP address ranges need to be accessible for the Level365 UC platform and devices to perform properly.
SIP-ALG should be disabled on any internet router or firewall. SIP-ALG is a common cause of various issues including poor call quality, telephone registration problems, and other inconsistent telephone behaviors. Level365 has a network assessment tool that can help identify if SIP-ALG might be enabled on your network.
