4. ini File Configuration
Parameter
Description
[0]
= Disregard the silecesupp attribute (default).
[1]
= Handle incoming Re-INVITE messages that include the
silencesupp:off attribute in the SDP as a request to switch to
the Voice-Band-Data (VBD) mode.
EnableRport
Enables / disables the usage of the 'rport' parameter in the Via
header.
[0]
= Enabled.
[1]
= Disabled (default).
The device adds an 'rport' parameter to the Via header of each
outgoing SIP message. The first Proxy that receives this message
sets the 'rport' value of the response to the actual port from which
the request was received. This method is used, for example, to
enable the device to identify its port mapping outside a NAT.
If the Via doesn't include 'rport' tag, the destination port of the
response is taken from the host part of the Via header.
If the Via includes 'rport' tag without a port value, the destination
port of the response is the source port of the incoming request.
If the Via includes 'rport' tag with a port value (rport=1001), the
destination port of the response is the port indicated in the 'rport'
tag.
