RTP Port
: UDP port dedicated to the RTP communication, this is the
actual port for the audio streaming. By default the number 5004 is
reserved.
Disconnect Timeout
: if no audio streaming is received when the
Disconnect Timeout expires, the audio communication will be finished.
With regard to the address configuration, there are three different possibilities:
Local IP Address
:
In case the SIP connection will be made on a LAN
environment, the user should tick the ‘Local Address’ checkbox.
Public IP Address
:
This parameter is necessary when making
connections through a router to the Internet, and the public IP address is
known by the user.
8
The user must copy the public IP address of his
router into this box.
STUN Server & request period
:
It is possible to use the STUN protocol
to get the public IP address of the unit when connecting to a WAN
network by using a NAT enabled device such as a modem or a router, and
the user is not aware of that address. Just by entering the IP address of
a STUN server, the unit will get that information from it. The ‘Request
Period’ defines how often the unit will ask for this information and refresh
the public IP address value. This information might change quite often
depending on the type of connection.
The next step to follow for the SIP configuration is to set up the SIP Server
configuration parameters
9
:
8
Routers translate local or private IP addresses into public WAN IP addresses (e.g. Internet).
This translation of address is broadly known as NAT.
9
A SIP account must have been enabled in the corresponding SIP server for this to work. Please
ask for these parameters to the corresponding IT department or SIP provider.
