Configure the IP address or URL for the VoIP provider 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".
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 "Keep Trunk CID" is enabled, 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.
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.
Configure the maximum number of concurrent calls allowed over the trunk
at the same time. The default value is 0 meaning no limit.
Enable to detect Fax signal from the trunk during the call and send the
received Fax to the default Email address in Fax setting page under web
GUI->PBX->Internal Options->Fax/T.38.
Note:
If enabled, Fax Pass-through cannot be used.
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.
