Port pages in the GXW40xx.

• SIP User → Sip User ID and Authenticate ID

• Password → Password

• UDP Port → The GXW assumes port 5060

as the default value. If other port number is
given, append it to the Primary Sip Server
URL using a colon and the port number (e.g.
Port 6060 sip.skype.com:6060).

• STUN address → Set Nat Traversal (STUN)
to YES and enter the address in Advance
Settings page > Stun Server
