Hi :) First of all: A Happy New Year :) Well, I am new to this list also to SER and SEM. My problem is: SER 0.8.14 runs quite good but I have problems to communicate with SEM. I always get: 9(1095) ERROR: fifo_server: command t_reply is not available 9(1095) ERROR: fifo_server: command must have at least 3 chars 9(1095) ERROR: fifo_server: command must begin with :: 0000018F22AC47B1 9(1095) ERROR: fifo_server: command must begin with :: Content-Type: application/sdp 9(1095) ERROR: fifo_server: command must begin with :: v=0 9(1095) ERROR: fifo_server: command must begin with :: s=session 9(1095) ERROR: fifo_server: command must begin with :: t=0 0 9(1095) ERROR: fifo_server: command must begin with :: a=rtpmap:0 PCMU/8000 9(1095) ERROR: fifo_server: command t_reply is not available 9(1095) ERROR: fifo_server: command must begin with :: could not send response. 9(1095) ERROR: fifo_server: command must begin with :: 0000018F22AC47B1 9(1095) ERROR: fifo_server: command must have at least 3 chars After searching the archives I found a posting written in August 04. The answer was that there might be a problem concerning the versions of SER and SEM. As I said, I run SER 0.8.14 and downloaded SEM via CVS. So, do I have to compile SER from CVS version? TIA and kind regards, Hauke
