Meridian Mail Trunk Access Restriction
MTAR is triggered if the network information (such as Network Attendant
Service or Calling Line Identification) indicates that an external call and a
transfer/conference attempt to Meridian Mail is occurring. MTAR is also
triggered if local information, such as Route Class, indicates an external call
and a transfer/conference attempt to Meridian Mail is occurring.
Meridian Mail Trunk Access Restriction averts potential Meridian Mail
system abuse by distinguishing between internal and external calls that are
directed to Meridian Mail. When activated, Meridian Mail Trunk Access
Restriction impacts the operation of the following features:
• Call Transfer
• Conference,
• No Hold Conference, and
• Call Join capabilities of the Multi-Party Operation feature.
Meridian Mail Trunk Access Restriction prevents the completion of any Call
Transfer, Conference, No Hold Conference or Call Join attempts on
incoming/outgoing external calls to Meridian Mail.
As illustrated in Figure 100, MTAR capabilities prevent an established call
between Set A, an internal call, and Set B, an external call, from being
forwarded to Meridian Mail. When Set A attempts to either Transfer,
Conference, No Hold Conference or Call Join Set B to Set C, which is either
a direct Meridian Mail DN or has activated Call Forward All Calls (CFAC)
to Meridian Mail, the transfer and conference keys are ignored when pressed
to complete operation.
