I've come across your tip meanwhile, I haven't been aware of this, thanks! Sadly, the existing installation has a large number of SPA 900 series phones that IIRC can't be scripted this way. Besides, as you say, it's really not an acceptable workaroun...

We have the same issue and -- exactly as you've said -- it's a dealbreaker. One customer already stopped considering Cisco phones for a new installation based on this.

We have the same issue. The fact that there seems to be no way of clearing the call lists remotely makes this even more unbelievable. It's definitely a showstopper for any large deployment.
