Table 52: SIP Register Trunk Configuration Parameters
Configure a unique label to identify this trunk when listed in outbound rules,
inbound rules etc.
Configure the IP address or URL for the VoIP provider’s server of the trunk.
Configure the SIP transport protocol to be used in this trunk. The default setting is
"UDP".
• UDP
• TCP
• TLS
SIP URI Scheme
When Using TLS
When TLS is selected as Transport for register trunk, users can select between
SIP and SIPS URI scheme
Keep the CID from the inbound call when dialing out. This setting will override
“Keep Trunk CID” option. Please ensure that the remote peer PBX supports
matching user entry via the "username" field from authentication line.
If enabled, the trunk CID will not be overridden by extension’s CID when the
extension has CID configured. The default setting is “No”.
Turn on this option 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 configuration on the firewall.
If selected, 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.
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.
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.
Allow outgoing calls

If enabled, outbound calls can still be made even if registration to the trunk fails.
Note: If Need Registration is disabled, this option will be ignored.
Configure the new name of the caller when the extension has no CallerID Name
configured.
Configure the domain name of the SIP user account. This will overwrite the
domain in the "From" header. Example: If the user account is "1234567", setting
