We are currently expecting problems with putting calls on hold and retrieve them later on. The problem is, that the call cannot be retrieved, the un-hold button is greyed out. This is only temporary. We are running IPCC version 7, this happens with CAD and CTI OS. This is happening with both, so that I'm thinking it could be a CTI problem.

As mentioned before this is not a permanent error. Anyone seen this before?
this does indeed look like a third party control problem occuring on the CTI side, I would suggest to raise a TAC SR for similar complex scenarios.
