Router compatibility depends on the model, firmware, network configuration, and phone service. Keep firewall protection enabled and have your network administrator check SIP ALG, network traversal, and the provider’s required traffic rules. The model notes below were published in 2016; confirm the current hardware revision and firmware before relying on them.
