Direct Outward Dialing (DOD) via VoIP Trunks

The UCM6510 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 UCM:
1. To setup DOD go to UCM6510 web GUI->PBX->Basic/Call Routes->VoIP Trunks page.
Select audio and video codec for the VoIP trunk. The available codecs are:
PCMU, PCMA, GSM, AAL2-G.726-32, G.726, G.722, G.729, G.723, iLBC,
ADPCM, VP8, H.264, H.263, H.263p.
If enabled, the UCM6510 will regularly send SIP OPTIONS to the device
to check if the device is still online. The default setting is "No".
When "Enable Qualify" option is set to "Yes", configure the timeout (in ms)
for the 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".

None: Disable Fax.

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.
