I check many times RTP stream and resulting sound in speakers (using PlaceCall_dbg.exe), and problem with random sound mute on speakers not in wrap from 65535 to 0, because this problem occurs and when rtp seq=20000...30000, etc. -- Best regards, Alexey [ [EMAIL PROTECTED] ] _______________________________________________ sipxtapi-dev mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipxtapi-dev/
