One of our customers has a helpdesk which roughly 12-15 phones belong to.
All of them are setup with the same CSS and Parition apart from 1 phone.
For some reason, this particular phone can't be dialled from an external source, or have calls transfered to it when it resides in the same partition as all of the other phones.
But if we put it into another partition, then it can be.
I don't understand what could be causing this, as obviously routing through to that particular partition is A-Ok, as the other phones in it can receive calls and transfers no problem.
