To use SIP VoIP calls in your phone, create and configure a SIP account by using the settings you have got from your VoIP service provider.

A sample SIP configuration is shown below with the following settings:

  • SIP address (public user name) = 123456@voipservice.com
  • User name = 123456
  • Password = xxxxxx
  • Outbound proxy = voipservice.com

To set up the SIP account, proceed as follows:

  • Select Accounts > Add accounts > SIP and define:
    • SIP address (public user name): 123456@voipservice.com
    • Password: xxxxxx
  • Select Advanced settings and define:
    • Use for telephone calls: ON
    • Username: 123456
    • Transport: Automatic

    • Discover public address: ON

After you have defined the settings, select Sign-in to sign in to your SIP service provider.
