Table 52: SIP Peer Trunk Configuration Parameters
Basic Settings
Provider Name
Configure a unique label to identify this trunk when listed in outbound rules,
inbound rules and etc.
Host Name
Configure the IP address or URL for the VoIP provider’s server of the trunk.
Transport
Configure the SIP transport protocol to be used in this trunk. The default setting is
"UDP".
• UDP
• TCP
• TLS
Keep Original CID
Keep the CID from the inbound call when dialing out, this setting will override “Keep
Trunk CID” option. Please make sure that the peer PBX at the other side supports
to match user entry using “username” field from authentication line.
Keep Trunk CID
If enabled, the trunk CID will not be overridden by extension’s CID when the
extension has CID configured. The default setting is “No”.
NAT
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’s related to NAT
configuration or SIP/RTP port configuration on the firewall.
Disable This Trunk
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.
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.
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 SettingsGeneral Settings will be used.
CallerID Name
Configure the name of the caller to be displayed when the extension has no
CallerID Name configured.
