Primary SIP Server
SIP Server’s IP address or Domain name provided by VoIP service provider.
Failover SIP Server
Failover SIP Server’s IP address or Domain name in case primary server does not
respond.
Prefer Primary SIP
Server
Default is
No
. If set to yes, it will register to Primary Server if registration with Failover
server expires
Outbound Proxy
IP address or Domain name of Outbound Proxy, or Media Gateway, or Session Border
Controller. Used by DP715 for firewall or NAT penetration in different network
environments. If symmetric NAT is detected, STUN will not work and ONLY outbound
proxy can correct the problem.
SIP transport
User can select UDP or TCP or TLS. Default is
UDP.
NAT Traversal (STUN)
This parameter defines whether or not the DP715 NAT traversal mechanism is activated.
If activated (by choosing “Yes”) and a STUN server is also specified, then the DP715
performs according to the STUN client specification. Using this mode, the embedded
STUN client will detect if and what type of firewall/NAT. If the detected NAT is a Full
Cone, Restricted Cone, or a Port-Restricted Cone, the DP715 will use its mapped public
IP address and port in all of its SIP and SDP messages.
If the NAT Traversal field is set to “Yes”
with no specified STUN server
, the DP715 will
periodically (every 20 seconds or so) send a blank UDP packet (with no payload data) to
the SIP server to keep the “hole” on the NAT open.
DNS Mode
One from the 3 modes are available for “DNS Mode” configuration:
-A Record (for resolving IP Address of target according to domain name)
-SRV (DNS SRV resource records indicates how to find services for various protocols)
-NAPTR/SRV (Naming Authority Pointer according to RFC 2915)
One mode can be chosen for the client to look up server.
The default value is “A Record”
Tel URI
The default setting is
“Disabled”.
If the phone has an assigned PSTN
Number, this field should be set to “User=Phone” then a
“User=Phone” parameter will be attached to the “From header” in the SIP
request to indicate the E.164 number. If server supports TEL URI format, then this option
needs to be selected.
