The VoIP trunk options are listed in the table below.
Table 51: Create New SIP Trunk
Configure a unique label (up to 64 character) to identify this trunk when listed in
outbound rules, inbound rules etc.
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”.
