I've got a Merlin Legend (CKE3, hardware vintage 00, R7.0, v10.0) system with a pair of 408 MLX GS/LS-ID modules (hardware vintage 12, firmware vintage 42, application vintage 31, upgradeable). We have caller ID (with calling party name) service from our local telco.
For calls with both name and number, the system works like a charm.
However, for calls with a number but without a name (name is "Out of Area", e.g. for wireless callers), the system claims there's no caller ID data. (I verified this by plugging in a caller ID phone directly into one of our trunks. I see "Out of Area / 617-792-3222".)
Is this a fundamental limitation of these caller ID modules? Is it fixable by a firmware upgrade? A processor upgrade?
On a related note, is there any way to get MLX phones to display both name and number simultaneously, without having to sacrifice one of the programmable buttons?
