&net.rtp.ifdst
Parameter to define IP address for RTP relay between Brekeke SIP Server and UAS. (available v3.7.6 or later)
Syntax:
&net.rtp.ifdst = <IP address> or &net.rtp.ifdst = <IP address>:<port>
*If <port> is not specified, BSS will not replace the port value on SDP.
* This parameter can be used in the case RTP relay is Off.
Explanation:
When Brekeke SIP Server has multiple IP addresses, an appropriate IP address is automatically selected for relaying RTP packets. However, you can also specify an IP address that is used for relaying RTP packets at each Dial Plan rule in the case such as controlling RTP route/traffic.
With the parameter, Brekeke SIP Server automatically binds an IP address and overwrites connection information at SDP header for RTP relay.
Example:
<Brekeke SIP Server>
The server has the following 4 IP addresses:
192.168.1.1
192.168.1.2
192.168.1.3
192.168.1.4
<UAC>
192.168.1.20
<UAS>
192.168.1.30
&net.rtp.ifdst = 192.168.1.4
RTP packets between Brekeke SIP Server and UAS are relayed with the following IP addresses;
UAC(192.168.1.20) <—–RTP packets—–>(192.168.1.X)Brekeke SIP Server (192.168.1.4) <—-RTP packets—–>UAS(192.168.1.30)
