GXP2135 caller ID not showing up to receiver



We’ve recently installed GXP2135 phones in our London office. They’re great, although our caller ID doesn’t show to anyone we call outside the office.

Any ideas on how to fix this?




Not without knowing to what the phones are connected to -provider, PBX, etc.


I’ve seen this happen when someone changes the caller ID to the name of the person instead of the extension.

Just saying…
