Turn on this setting when the PBX is using public IP and communicating
with devices behind NAT. If there is one-way audio issue, usually it is
related to NAT configuration or SIP/RTP port support on the firewall.
If checked, the trunk will be disabled.
Note:
If a current SIP trunk is disabled, UCM6510 will send UNREGISTER
message (REGISTER message with expires=0) to the SIP provider.
If the trunk has an assigned PSTN telephone number, this field should be
set to "User=Phone". Then a "User=Phone" parameter will be attached to
the Request-Line and TO header in the SIP request to indicate the E.164
number. If set to "Enable", "Tel:" will be used instead of "SIP:" in the SIP
request. The default setting is 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.
Select whether the trunk needs to register on the external server or not
when "Register SIP Trunk" type is selected. The default setting is No.
Enter the username to register to the trunk from the provider when
"Register SIP Trunk" type is selected.
Enter the password to register to the trunk from the provider when
"Register SIP Trunk" is selected.
Enter the Authentication ID for "Register SIP Trunk" type.
Enable automatic recording for the calls using this trunk (for SIP trunk
only). The default setting is disabled. The recording files can be accessed
under web GUI->CDR->Recording Files.
