Endpoint sends the register request to FreeSBC however the FreeSBC is not forwarding it to the registrar

[Admin]

The endpoint sends the register request to FreeSBC however the FreeSBC is not forwarding it to the registrar. Please check the following points to solve this issue;

• Check if SIP domain configured correctly. https://docs.telcobridges.com/tbwiki/Toolpack:Creating_a_SIP_Domain_SBC_A
  
  
• Check the SIP domain Status. Be sure domain registrar can be reached by FreeSBC. To check, Go to Status -> SIP -> SIP Domain -> Status -> SIP Registration Domains
  
  
  
• Check if SIP client configured correctly to send correct Domain name to FreeSBC. You can capture a SIP trace (see Signaling trace capture tool ) and use wireshark to analyze the trace. Look at the “To:” SIP header: it must match what is in the Sıp Domain configuration of the FreeSBC.
