outside line available for
dialing calls.

is not being honored.
I cannot make an outgoing

reserved trunks.

are not directed to the
selected extension.

Troubleshooting
Synapse Administrator's Guide
Probable Cause
Incoming calls can use
reserved trunks or channels.
All available channels may
be busy with the incoming
calls.
An incoming call may be
using that line. Parking calls
and forwarding calls on a
reserved trunk does not free
up the trunk.
All lines and channels are
being used for active or
incoming calls, or are
reserved for other
extensions.
Direct Dial is not enabled
The first digit of the
extension matches an Auto
Attendant Menu item.
The first digit of an extension
number matches the first
digit of parked calls.
Corrective Action
Wait for an available channel or contact your service
provider to add more voice channels.
Set up Trunk Routing to reserve the incoming path to the
'special' extension. On the administrator WebUI, click
System Settings, then Trunk Routing.
Forwarded call must end before the reserved trunk is
available.
If all trunks are reserved, extensions with trunk
reservations cannot make calls. The SA can either remove
the reservations from some trunks or arrange for
additional analog telephone lines or T1 channels.
Enable Direct Dial. On the administrator WebUI, click
System Settings, then Direct Inward Dial, and verify
the Current DID Ranges. Then click
Ensure that the first digits of the extension numbers do
not match the Auto Attendant menu choices. Change the
Auto Attendant menu choices or the first digits of the
extensions so they do not match.
Correct your dial plan. Do not have extension numbers
whose first digits match the park extension prefix. On the
administrator WebUI, click System Settings, then Dial
Plan Settings.
