Create a SIP Extension

Yeastar K2 IPPBX supports Session Initiation Protocol (SIP). SIP is used in VoIP communications allowing users to make and receive voice calls for free over the Internet. Before registering a SIP account on phones, you need to create a SIP account.

   • Type: Select the checkbox of SIP.
   • Extension: Enter the extension number.
   • Caller ID: Enter the caller ID number. The called party will see this caller ID number when the extension user makes an outgoing call.
   • Caller ID name: Enter the caller ID name. The called party will see this caller ID name when the extension user makes an outgoing call.
   • Emergency Outbound Caller ID: Enter the outbound caller ID for emergency calls. The PSAP (Public Safety Answering Point) can pinpoint the user's location based on the caller ID.

   • Registration Name: The name used to register a SIP extension.
