[cisco-voip] Strange Call Hold Behavior

We are using RCC with MOC 2007 R2.  We're thinking a recent update on OCS may be causing the issue as we've been on this firmware code  on the 9971 for about 3 months and the 7975 code/CUCM version since this time last year.

The intermittent nature as well as our newly reported 'stuck call' issue makes your CTI idea very solid.

Very odd.

Those 2 phones use different code bases.  This makes it very likely an event is coming in from elsewhere and triggering this behavior.  Check the CM SDI/SDL traces to see what event is initiating the hold.

Given the resolution it seems highly likely that a CTI application is controlling the phones and causing the behavior.  Deleting and readding the phones would disallow any existing CTI control.

We've seen similar in the past in call centers when auto answer was enabled on the phone and in CAD.

Sorry for the no subject guys.   Bug toolkit doesn't show anything which matches this behavior.

I have a strange phone issue with 9971 on 9.2.1 and 7975 on 9.0.3

CUCM is 8.0.3

When a cisco user calls a number and the call is answered, it is immediately placed on hold.

Changing the mac and rerunning TAPS resolves the issue but isn't what I consider a sloution.

Any thoughts?
