New question #219552 on rohc: https://answers.launchpad.net/rohc/+question/219552
Hello team, I am using rohc 1.5.1 on 2 servers Centos 4.x and 5.x. I installed from sources following your wiki and tunnel is up with data transfer OK. It seems to be working fine but I need rohc to compress RTP flow, so I set up a tunnel on 2 asterisks and created a sip trunk in this rohc tunnel. Here is the command I use: /opt/rohc/sbin/rohctunnel rohc0 remote "public ip 1" local 192.168.1.50 port 5000 3> /opt/rohc/comp_stats 4> /opt/rohc/decomp_stats & and: /opt/rohc/sbin/rohctunnel rohc0 remote "public ip 2" local "public ip 1" port 5000 3> /opt/rohc/comp_stats 4> /opt/rohc/decomp_stats & I use local IP on server 1 because it is behind a router. It is up and sip calls (g729) connect. However, I need to verify rohc's compression rate. Thus, I used 2 different tools to monitore bandwidth: iftop and a router calculating BP stats. My problem is that a call going through rohc takes as much BP as a non compressed one (about 30kb/s). I tried up to 3 calls and no difference were noticed. Compression logs during call shows that it is working: 206 O-mode SO 60 28 36 4 0 FYI, asterisk trunks are set with "canreinvite=no" to be sure that RTP goes through the tunnel and not directly to the public IP. Does anyone have an idea?
