1.2.8 To Access Another Party Directly from Outside (Direct Inward System Access [DISA])

When you receive an outside call via DISA, for example to your cellular phone, it is possible to transfer the call to an extension in the PBX, or establish a conference call by pressing # + desired extension number (if enabled through system programming). Calls can only be transferred to extensions within the PBX.

* Callers from preprogrammed outside numbers can access the PBX through DISA without a password (extension PIN/verification code PIN) (DISA Automatic Walking COS).

When making an outside call using Walking COS through DISA, the CLIP number for that call will be that of the extension seized by Walking COS.
