Our customer asked me about automedia bypass configuration on SBC2200. After I guided them to set this configuration on SBC,
they asked me to prove them that now the media path is not going through SBC and RTP packets are transferring just in private network.
The SBC2200 version was SessionEngine2200-VRP3.30-0233(SBCV200R003B02D033).
In order to be sure that the automedia bypass function has been enabled on the SBC, and RTP packets are not going through SBC anymore,
we can follow these steps:
1.Before enabling automedia bypass function execute following commands on SBC:
i. <SBC2200> debugging sbc rtp packet
ii.<SBC2200> terminal debugging
iii.<SBC2200> terminal monitor
2. Now make a call, you will see the stream of RTP packets which are going through SBC and this stream will be displayed on the screen
(refer to the attached file named "debug information with automediapass disable.TXT"). In order to get rid of lots of information wich is displayed on the screen
you can disable above commands by using "undo" keyword before each of the above commands.
3.Then enable the automedia bypass function on the SBC and execute following commands:
i- <SBC2200> debugging sbc mediapass all
ii- <SBC2200> debugging sbc rtp packet
iii-<SBC2200> terminal debugging
iv-<SBC2200> terminal monitor
4. If you make a call in this time you will see that no RTP packet stream is displayed on screen (refer to the attached file named "debug information with
automediapass enable.TXT"). By comparing this situation with the last one, you will be sure that in this case no RTP packets are going through SBC.
