Direct Outward Dialing (DOD)

The UCM6200 provides Direct Outward Dialing (DOD) which is a service of a local phone company (or
local exchange carrier) that allows subscribers within a company's PBX system to connect to outside lines
directly.
Example of how DOD is used:
Company ABC has a SIP trunk. This SIP trunk has 4 DIDs associated to it. The main number of the office
is routed to an auto attendant. The other three numbers are direct lines to specific users of the company.
At the moment when a user makes an outbound call their caller ID shows up as the main office number.
This poses a problem as the CEO would like their calls to come from their direct line. This can be
accomplished by configuring DOD for the CEO's extension.
Steps on how to configure DOD on the UCM6200:
1. To setup DOD go to UCM6200 web GUI->PBX->Basic/Call Routes->VoIP Trunks page.
2. Click to access the DOD options for the selected SIP Trunk.
3. Click "Create a new DOD" to begin your DOD setup
4. For "DOD Number" enter one of the numbers (DIDs) from your SIP trunk provider. In the example above
Company ABC received 4 DIDs from their provider. ABC will enter in the number for the CEO's direct
line.
Qualify SIP message. If no response is received within the timeout, the device is
considered offline. The default setting is 1000ms.
When "Enable Qualify" option is set to "Yes", configure the interval (in seconds) of
the SIP OPTIONS message sent to the device to check if the device is still online.
The default setting is 60 seconds.
The maximum number of concurrent calls using the trunk. The default settings 0,
which means no limited.
Select Fax mode. The default setting is "None".


Fax Detect: Fax signal from the user/trunk during the call can be detected and
the received Fax will be sent to the Email address configured for this
extension. If no Email address can be found for the user, the Fax will be sent
to the default Email address configured in Fax setting page under web UI-
>PBX->Internal Options->Fax/T.38.
