[Freeswitch-users] Media got stuck after attended transfer...

Hi, sometimes I have the problem that after doing an attended transfer the media got stuck in FS. Meaning the call goes through, but I don't hear anything and the caller still hears music. Now I found out that setting the sofia parameter media-option=resume-media-on-hold helps here. But after setting this parameter I always get the error "Codec PROXY PASS-THROUGH encoder error!" when using t38modem with proxy_media=true. So I stuck here. I can either use fax or do attended transfers. Does anyone have a solution for this? Thanks, Klaus
