SIP Setting
This page allows you to configure the settings related to the SIP service provider. You need to configure your
VoIP Adapter to communicate with the devices that will send and receive telephone calls over the Internet.
If you are behind a NAT modem or router, you may have to use a STUN server.
Signaling Port
Enter the signaling port to send and receive SIP message for building a session.
The default value is 5060 and this must match with the peer Registrar when
making VoIP calls.
RTP Start
Specifies the start port for RTP stream. The default value is 40000.
RTP End
Specifies the end port for RTP stream. The default value is 50000.
STUN
Enable or disable STUN server feature.
Server Address
Enter the STUN server IP address if you enabled the STUN server feature.
NAT Keep Alive Time
Check the checkbox and enter the time period for the NAT to keep alive.
Rport
Check this checkbox to use rport. Rport, or symmetric signaling, is critical for
operations behind some classifications of NATs. If enabled, the SIP stack will
send outbound SIP messages on the same port that it listens on. Unless you are
familiar with single SIP port, it is better to use rport.
T.38 Fax Protocol
Check the checkbox if the remote end also supports FAX function.
P_Assert
Check the checkbox to enable P_Assert to hide the client name when sending
messages to the SIP proxy server.
