Hi We've recently upgraded from version 1.0.head to 1.2.0-rc2 and noticed that certain events sent from php code using the ESP library have certain core headers missing, in particular 'FreeSWITCH-Hostname'. For example, using '/events plain all' in fs_cli, version 1.0.head would show RECV EVENT Event-Subclass: rmCTI::TRANSFER_ANSWER Core-UUID: 47527f1f-b6c3-4f74-9f16-32f565ee4123 FreeSWITCH-Hostname: s01pbx01.test.com FreeSWITCH-Switchname: s01pbx01.test.com FreeSWITCH-IPv4: 211.141.141.131 FreeSWITCH-IPv6: ::1 Event-Date-Local: 2012-08-03 10:43:06 Event-Date-GMT: Fri, 03 Aug 2012 09:43:06 GMT Event-Date-Timestamp: 1343986986238409 Event-Calling-File: mod_event_socket.c Event-Calling-Function: read_packet Event-Calling-Line-Number: 1188 Command: sendevent CUSTOM Event-Name: CUSTOM Channel-Name: sofia/internal1/1202@sip.test.com rmCTI-UUID: aebc98dc-22da-4ad1-8234-912487329123 rmCTI-Other-UUID: b24a8783-16b1-495e-9c4e-5ea52c362123 rmCTI-Info: Transfer to new b-leg answered where as version 1.2.0-rc2 it shows RECV EVENT Event-Subclass: rmCTI::TRANSFER_ANSWER Command: sendevent CUSTOM Event-Name: CUSTOM Channel-Name: sofia/internal1/1202@sip.test.com rmCTI-UUID: c3c7b331-0b8b-4ea5-834f-9d72fd446123 rmCTI-Other-UUID: db75c60b-a258-4b47-8d51-a1b7ac86f123 rmCTI-Info: Transfer to new b-leg answered Event-UUID: f47597b2-9e8c-4508-be57-3e1eed35c123 Is there any reason these core headers are missing? Is it something to do with CUSTOM events? Thanks in advance James Bravo
