Configure the IP address or URL for the VoIP provider's server of the
trunk.
If enabled, the trunk CID will not be overridden by extension's CID when
the extension has CID configured. The default setting is "No".
If selected, the trunk will be disabled.
Configure the Caller ID. This is the number that the trunk will try to use
when making outbound calls. For some providers, it might not be possible
to set the CallerID with this option and this option will be ignored.
When making outgoing calls, the following rules are used to determine
which CallerID will be used if they exist:

The CallerID configured for the extension will be looked up first.

If no CallerID configured for the extension, the CallerID configured for
the trunk will be used.

If the above two are missing, the "Global Outbound CID" defined in
Web GUI->PBX->Internal Options->General will be used.
Configure the name of the caller to be displayed when the extension has
no CallerID Name configured.
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, H.264, H.263, H.263p and VP8.
If enabled, the UCM6200 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.
