Step 2:

Fill the followings fields.

• SIP Server: atlanta.voip.ms (one of our multiple servers)
• SIP User ID: 100000 (Your VoIP.ms username)
• Authenticate Password: ********* (Account Password)
• User ID is phone number: No
• SIP Registration: Yes
• Register Expiration: 180
• NAT transversal : No
  • Notes: NAT transversal 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] )
