Hello, I have this toplogy: CW--->FS--->SIPGW What I want to achieve is to send RTP continuously to CW as it cannot handle CN, but I would like to use CN between FS and that SIPGW (I don't know what is that equipment). Is this possible? I tried to play with supress_cng option but don't really know how should I manage this case. In sofia profile I have suppression commented out: <!-- <param name="supress-cng" value="true"/> --> and I tried before bridge: <action application="set" data="supress_cng=true"/> and <action application="set" data="supress_cng=false"/> Any idea? Thanks in advance, Tamas
