Configure the provider name for the VoIP trunk. This is a unique label to
identify the trunk when listed in outbound rules, inbound rules and etc.
Configure the IP address or URL for the VoIP provider server of the trunk.
When enabled, it can avoid overridden by extension's CID if the extension
has CID configured. The default setting is enabled.
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.
Enter the username to register to the trunk from the provider.
Enter the password to register to the trunk from the provider.
This is the authentication ID for the UCM6510 to register to the trunk if
required by the provider. If not specified, the CallerID name will be sued
for authentication.
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 and H.263p. In the selected codec list,
users can click on UP or DOWN arrow to adjust the order for the codec
priority.
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.
