Below is a method that you should be able to use to extract telephone call history (both incoming and outgoing) from the Siemens OpenScape Office Telephone System. There is a tool called myReports that can be used to extract more detailed call information, but in my case, access to this tool was not available to me due to not having the relevant licensed modules on our telephone system.
Telephone System: Siemens OpenScape Office
Client PC: Windows 7 64Bit
Required Information (my environment details [not real!])
Telephone Server IP: 192.168.1.50
Telephone Server Username: MYUSERNAME@system
Telephone Server Password: MYPASSWORD
Method 1 - Call log information via Telephone Server URL
After trying to un-successfully run the Siemens myReports Software, a few Google searches later, I came across a PDF download from the Siemens Wiki Site (OpenScape Office V3 - Call Detailed Recording & Call Data Record Structure 2012-07-24) which referenced accessing the servlet available on the telephone system to retrieve call log information. Page 7 of this document indicated that a specially crafted URL containing a valid HTTP interface log in username and password within the parameters would allow access to call log information.
I tried this URL adjusting it to my environment and managed to get all our outgoing call information using:-
I could then see the following outgoing (info on how to change this is below...) call information in my web browser
