Parameter Description:
• SIP Domain: IP Telephony SIP Proxy Server domain name. It’s normally
used when you have a DNS record setup for SIP Proxy Server.
• Listen UDP Port 2 and Port 3 : The local UDP ports on which the SIP service
listened
- Encrypt: Both SIP signal and voice RTP packets can be encrypted while
passing through the UDP port. This feature is used to avoid ISP blocking
VoIP services. The encryption protocol is Welltech’s proprietary and need
to install Welltech’s SIP IP devices to work.
• Enhance Service Port : The listen UDP port for enhance service.
• MWI Service Port: The listen UDP Port range for MWI (Message Waiting
Indication) Service (port 8080 to 8085).
• Subscriber Login: Allow this Subscriber login to this IP-PBX or not.
• Support Video: Support Video RTP packets to pass-through between two
Video IP devices. If “Enable Video” was activated, it consumes a lot of
bandwidth and reduces the number of concurrent RTP calls largely.
• Forward Caller ID: (There are two options)
- Caller : Use original caller ID when call was forwarded to another user.
- Forwarder : Use forwarder caller ID when call was forwarded to another
user.
• Voice Gateway: Enabling voice gateway feature, SIPPBX 6200x will be able
to play the role as a NAT server to pass through SIP and voice call. Please
refer to Voice Gateway Example for a configuration example.
