when I login to the agent desktop, the following error pops up.Login could not be performed.possible causes are invalid instrument, media termination problem or CM issue.
I have installed 7.0ctios client along with ctios 7.1.4 release.
One cause of this problem is incorrect configuration of the device target. Do you have the "/devicetype ciscophone /dn xxxx" set? Other possibility - the phone is not associated with the ICM JTAPI user in Call Manager. Show trace on the JGWY process and watch what it says as the PG tries to set up an observer on the device.
Why don't you upgrade the CTIOS client to match your CTIOS?
