Steps

Customers can authenticate via three ways:

1. REGISTER incl. DIGEST Authentication (username + password)
1. SIP REGISTER prerequisites:
1. - The CONTACT and FROM headers must contain the username in the ‘user’ part- When sending the INVITE:
2. The CONTACT header must be identical as with the REGISTER message
3. It must contain the REMOTE-PARTY-ID or P-ASSERTED-IDENTITY header, to include a valid CLI
   
   
2. SIP INVITE incl. DIGEST Authentication (username + password)
1. Resulting in a SIP 407 Digest Authentication required challenge
   
   
3. IP based authentication/Trustes IP
   
   Per special request done via [email protected] or your account manager we offer the possibility of IP based authentication. This is ONLY possible for one single SIP account using the same SIP IP endpoint.
