Disable This Trunk
If checked, the trunk will be disabled.
Note: If a current SIP trunk is disabled, UCM will send UNREGISTER message
(REGISTER message with expires=0) to the SIP provider.
TEL URI
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.
Caller ID
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.
Important Note: When making outgoing calls, the following priority order rule will
be used to determine which CallerID will be set before sending out the call:
From user (Register Trunk Only) → CID from inbound call (Keep Original CID
Enabled) → Trunk Username/CallerID (Keep Trunk CID Enabled) → DOD →
Extension CallerID Number → Trunk Username/CallerID (Keep Trunk CID
Disabled) → Global Outbound CID.
Need Registration
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.
Username
Enter the username to register to the trunk from the provider when "Register SIP
Trunk" type is selected.
Password
Enter the password to register to the trunk from the provider when "Register SIP
Trunk" is selected.
Auth ID
Enter the Authentication ID for "Register SIP Trunk" type.
Auto Record
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.
Direct Callback
Allows external numbers the option to get directed to the extension that last called
them.
For Example: User 2002 has dialed external number 061234575 but they were not
reachable, once they have received missed call notification on their phone, they
would mostly call back the number, if the option “Direct Callback” is enabled then
they will be directly bridged to user 2002 regardless of the configured inbound
destination.
