I am getting this error when trying to use app_txfax. Program received signal SIGSEGV, Segmentation fault. [Switching to Thread 1078266208 (LWP 28837)] 0x0000003873a0b0df in __read_nocancel () from /lib64/tls/libpthread.so.0 (gdb) where #0 0x0000003873a0b0df in __read_nocancel () from /lib64/tls/libpthread.so.0 #1 0x0000000000489056 in read_char () #2 0x0000000000494350 in el_gets () #3 0x00000000004715dd in main (argc=Variable "argc" is not available. ) at asterisk.c:2414 I am using asterisk 1.2.11, spandisp-0.0.2pre26.tgz with the associated app_rxfax and app_tx. Installed it etc.... My call file is: Channel: SIP/box1_to_box2/76630808 Context: smvoice-faxout Extension: smvoice_faxout Priority: 1 RetryTime: 2 WaitTime: 20 MaxRetries: 0 Setvar: SMFAXFILE=/tmp/faxme.g3 my extensions.conf is: [smvoice-faxout] exten => smvoice_faxout,1,txfax(${SMFAXFILE}) Seems like it should have been straight forward. I can place NORMAL call files and box1_to_box2 works just fine. My SIP connection between box1 and box2 is not the issue (I think). Dialing 7 is my analog outside line. TO create my document I used oowriter, typed a couple sentences, exported to PDF, ran the command: gs -q -sDEVICE=tiffg3 -sPAPERSIZE=a4 -r204x196 -dNOPAUSE -sOutputFile=/tmp/faxme.g3 -- "$1" and passed that file as my SMFAXFILE. Any suggestion on what I have not done correct? Thanks, jerry
