  • SIP User ID: 100000 (Replace with your 6 digits Main SIP account UserID or Sub Account user name, i.e. 123456 or 123456_sub)

  • Name: (Enter any name you like)
  • SIP Registration: Yes
  • Register Expiration: 3 (This setting is in minutes not seconds)
  • NAT Traversal : No
    • Notes: NAT Traversal can be set to Yes if you are behind a router (even if you do not set a value in the STUN server field). Indeed according to the reference guide, with no specified STUN server, then the phone will only periodically (every 20 seconds by default) send a blank UDP packet (with no payload data) to the SIP server to keep the mapped port open on the NAT.
  • Home NPA: Empty (Some tests show that this field should be kept empty or you will encountered difficulties with some numbers ending with a busy signal [tested with 418 in home NPA, and a 1-877 number] )
