Hi, I want to know about the content of ast db. It is like a registry of the asterisk to store information about register users. The similar user register information will be stored in DB in ARA. I want to verify that when user sends a register request and it is valid, asterisk will capture the user information in ast db and also in rdbms. Then when the user makes a call request, asterisk will use ast db to form a request message. When there is a call to sip user, asterisk will use ast db to find the location of the user. Am I right? /SIP/Registry/871963596932 : 221.126.25.138:5060:60:871963596932:sip:871963596932@192.168.1.100:5060 /SIP/Registry/871966742968 : 210.184.23.31:15060:180:871966742968:sip:871966742968@10.0.0.118:5060 /SIP/Registry/871966760539 : 210.184.23.31:5060:60:871966760539:sip:871966760539@10.0.0.92:5060
