Dear AM, i would like to make media bypass for lower FS traffic, however, if i enable media bypass, the call transfer failed, the parameters as following, <param name="inbound-bypass-media" value="true"/> <param name="inbound-proxy-media" value="false"/> but if i disable media bypass like configuration below, call transfer works well. <param name="inbound-bypass-media" value="false"/> <param name="inbound-proxy-media" value="false"/> the scenario is very simple, PSTN user X->media GW->FS->Registered user A, A answer the call, then press hold button and dial B, A talked with B, A hangup the call, pstn user X should talk with B. Could you please advise if anything else i missed, i below FS so strong, it must support this scenario, i was suffered for this issue for over two years... thanks in advance. -- Regards, Charles
