[Freeswitch-users] Skypopen audio problems

Hi, i have a little problem i have FS installed, skypeopen_oss client and skypeopen.ko oss sound driver installed. I configure in public a DID number bridge to skypopen/RR/skype22, the call going from DID to SKYPE1 and call SKYPE22, here is the LOG: http://pastebin.freeswitch.org/17877 All work OK, but the sound from DID caller to Skype22 dont reach, no sound, Skype22 to DID caller works ok. Questions: Skype_oss and the skypeopen.ko require a sound card to work? What is the problem? Codecs? Please helpme, thanks and sorry my english.
