Table 51: Create New SIP Trunk
Type
Select the VoIP trunk type.
• Peer SIP Trunk
• Register SIP Trunk
Provider Name
Configure a unique label (up to 64 character) to identify this trunk when listed in
outbound rules, inbound rules etc.
Host Name
Configure the IP address or URL for the VoIP provider’s server of the trunk.
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 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.
