I wish to set up two PSTN calls and then connect them similar to Jajah (is this called 3pcc?). The PSTN interconnect is handled by a third party SIP provider. I can do this using the manager or call files. An example (using php) would be: fputs($oSocket, "Action: login\r\n"); fputs($oSocket, "Events: off\r\n"); fputs($oSocket, "Username: $strUser\r\n"); fputs($oSocket, "Secret: $strSecret\r\n\r\n"); fputs($oSocket, "Action: originate\r\n"); fputs($oSocket, "Channel: $strChannel\r\n"); fputs($oSocket, "WaitTime: $strWaitTime\r\n"); fputs($oSocket, "CallerId: $strCallerId\r\n"); fputs($oSocket, "Exten: $strExten\r\n"); fputs($oSocket, "Context: $strContext\r\n"); fputs($oSocket, "Priority: $strPriority\r\n\r\n"); fputs($oSocket, "Action: Logoff\r\n\r\n"); This simulates one extension calling another and has some limitations e.g. the CDR records show one call which doesn't meet my requirements for billing purposes. What's the best way to achieve this join up two calls scenario? Any suggestions appreciated. Cameron -------------- next part -------------- An HTML attachment was scrubbed...
