SIP ALG is the number one issue that will prevent phones registering to the platform. This is a setting that is quite often turned on automatically on most routers. Ensure SIP ALG is turned OFF on the router and firewalls.
MTU Size
The MTU size needs to be set as high as possible – eg. 1500ms / 1520ms
UDP Timeout
The UDP timeout needs to be set at >300s
(NAT Refresh/Inactivity Timer on your local network equipment - usually an edge firewall, router or NAT device)
Draytek Requirement
Under the Firewall Settings, Call and Data Filter need to be disabled along with the Strict Firewall. We also recommend the Routers Firmware needs to be on the Latest Version.
