I have several customers the use the same SIP Trunk provided. All inbound caller ID works well from any other provided but if it's from the same provider it only shows the last 4 digits. These companies have nothing in common except the provider and Avaya IP office systems.
The system are all 9.0 or 9.1 IP Offices and the provider installs Edgemarc SBC's at all locations.
any help would be appreciated
