VoIPBox BRI Version 18.0.002 Page 79
VoipRtpPort=<port>
Defines the starting UDP port used to transmit RTP packets (default 29000).
VoipRtpPortSpacing=<count>
Defines the space between the ports used for individual RTP streams (default 2).
H225Port=<port>
Endpoint-to-endpoint port (default 1720).
SipPort=<port>
SIP signaling port (default 5060). A different port for sending can be set in the
route.cfg
’s VoIP profile. Otherwise the port set here will be used for sending and receiv-
ing.
VoipMaximumBandwidth=<int>
Defines an upper limit for available bandwidth for the VoIP profiles to be configured
(see VoipBandwidthRestriction in Table 11.6
→
) if traffic shaping is active for the cor-
responding VoIP profile. Individual codecs are assigned the following values in kBit/s:
g711a, f711u, trp: 8
g72632, t38: 4
g72624 3
g72616, gsm 2
Other 1
You must define the list of codecs to be used in the VoIP profiles, whereby the codec
with the highest priority must be defined first. Calls will be set up using the codec with
the highest priority as long as the sum of the values for individual calls remains lower
than defined here. If the sum is greater, the next call will be set up with, and existing
calls will be switched to, a higher compression rate. Bear in mind that the VoIP peer
must support this feature.
VoipStrictRfc3261=<mode>
If yes is set, the SIP transaction/dialog matching will occur strictly as per RFC3261. You
must disable this feature for peers that use RFC2543 (from and to name). Default is
yes.
VoipLinger=<sec>
After an H.323 release complete has been sent, the TCP session will remain open for
the number of seconds entered if there is no response from TCP message sent so that
the system can resend the TCP packet.
StunServerAddress=<ip addr>
When this parameter is active, the VoIPBox looks for a (NAT) firewall in the network
and figures out how to bypass it without requiring changes. All ports for signaling, RTP
and RTCP are checked. The parameter VoipGlobalMaxChan defines the number of
ports for RTP and RTCP.
NOTE: This is not a solution for all firewall types.
StunServerPollInterval=<sec>
Interval (in seconds) for the stun request at each port (default 600).
Radius=<mode>
On (default) activates the Radius service. If you change Off to On, you must restart the
system.
