Parameter Description:
• SIP Domain: SIPPBX SIP domain name (i.e. avoip.com.tw). It’s normally used
when you have a DNS record setup for SIPPBX 6200x.
• Listen UDP Port, Port 2 and Port 3: The local UDP port on which the SIP
service listened. When you enable the encrypt option, this SIP license port
will use Welltech proprietary encryption SIP/RTP to avoid from ISR blocking
or security consideration. When an encrypted device talk to un-encrypted
device, SIPPBX 6200x will reroute the encrypted voice RTP back to SIPPBX
6200X to make them talking.
• TCP Enabled: Enable the local TCP port or not. For instance, 5070.
• Local TCP Port, Port 2 and Port 3: The local TCP port on which the SIP
service listened.
• No Answer Timeout: The default maximum time (in second) to wait for remote
party Answer (pick up phone).
• Max Forward Time: The maximum time to forward the calls.
• Default Max Register Time: The default maximum registering time for WAN
network user to register.
• Default NAT Max Register Time: The default maximum registering time for an
inside LAN user to register.
• Enable Device ACL: Authenticate specified device type or not.
• First Response Timeout: The default maximum time to wait for response. It
depends on the network delay time.
