Hi Paul,
I did a quick look and found few stuffs for you related to CTIOS and CTI Svr default tracing levels.
The following sections contain log file snippets with default tracing enabled:
•Desktop default trace level – 0x40000307
•CTI OS Server default trace level – 0x03
•CTI Server default trace level – 0xF0
•JTAPI Gateway default trace level – 0x00
Turn down to page 36 of following guide.
CTI OS Troubleshooting Guide for Cisco ICM/IPCC Enterprise & Hosted Editions Cisco CTI OS Release 7.2
http://www.cisco.com/en/US/docs/voice_ip_comm/cust_contact/contact_center/ctios/ctios7_2/troubleshooting/guide/ctits.pdf
Also attaching a Cisco doc which explaines how to raise ur tracing level. A good document detailing procedure for all processes and required value. I'd say - A must handbook for IPCC Support people.
Regards,
Soman Nair.
