LanScape VOIP Media Engine
SipWanIpAddressConfigError
This event may be sent to application software
when the application initiates a phone call. It allows application software
to detect if its wide area network (WAN) IP address has been configured
properly. The two primary causes of application call failures can be associated
with WAN IP address errors and router port translation issues. If your
telephony application communicates with another LanScape telephony product,
this event will always occur if a WAN IP address error is detected. If
your telephony application will communicate with other SIP user agents,
those user agents must support the SIP VIA header "received=x.x.x.x"
and "rport=xxxx" parameters.
