Troubleshooting Voice Trunks
Voice trunks are the telephone lines delivered to the carrier in digital or analog format (e.g., T1 or trunk
FXO lines). Trunk lines connect the NetVanta 7100 to the outside telephone network. The incoming lines
are linked to physical interfaces on the system. These interfaces control which resources are used for
outbound calls. This section covers the most common issues that prevent users from placing outbound
calls.
Checking the Port Status
Check the status of the telephone lines under the Physical Interfaces menu. The voice trunk interfaces are
FXO and T1. The physical interface names are formatted <interface type> <slot/port> (e.g., t1 0/1).
1. Navigate to
System > Physical Interfaces and check for green text in the Line Status of the
trunk and T1 interfaces. If the text under
Line Status is red, stop here and contact your network
administrator for assistance. Otherwise, continue to the next step.
2. If the
Line Status is OnHook or Up, your trunk line service is working properly. If the Line
Status
is Down, check the physical connection to your unit. If you suspect configuration or
network issues, contact your NetVanta 7100 system administrator.
