When you use a PCA, the MARP must be on the DN key of the phone
itself, not the PCA. If the MARP is on the PCA, CTI clients (such as
Office Communicator) do not receive Remote Call Control call pop-ups
for incoming calls (in addition to other problems). This is an unsupported
configuration.
Note that MARP is assigned to the first DN key created, so if you create
the PCA first and assign a DN key, it becomes the MARP by default. If
you add a phone later with the same DN (to twin the phone with Office
Communicator) the MARP stays on the PCA and you encounter this exact
situation. The following is an example of an unsupported configuration:
