Port settings on a Gigaset VoIP phone are usually set at 5060 but with some routers the VoIP traffic can cause issues and you may need to change the port to 5065 to get around issues such as firewalls blocking VoIP traffic which can impact on call quality. 


A port my also be blocked so by opening up another port this can resolve issues such as a phone failing to register.
