T#8091: Voice CallLog filter

Browse source 
- Show only one incoming record for each session.
- Add VoiceService.1.CallLog.{i}.UsedExtensions which include all involved Extensions during an incoming call.
- Change VoiceService.1.CallLog.{i}.Destination to the Extension that answers the incoming call if more than one Extension is involved
- The UsedLine uses the same inst number as the SIP Client involved.
- Removed the eliminated `master_old.csv`
