Configure the actual user name of the extension. This can be used to
override the From Header. There are cases where there is a single ID for
registration (single trunk) with multiple DIDs.
For example, "1234567" is the From User in From Header:
sip:1234567@trunk.UCM6510.provider.com.
If enabled, the SIP INVITE message sent to the trunk will contain PPI
(P-­Preferred-­Identity) header. The default setting is "No".
Note:
"Send PPI Header" and "Send PAI Header" cannot be enabled at the
same time. Only one of the two headers is allowed to be contained in the
SIP INVITE message.
If enabled, the SIP INVITE message sent to the trunk will contain PAI
(P-­Asserted-­Identity) header. The default setting is "No".

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.
