dears i have the following codes
both are running on the same server ( not at the same time )
when i run the unlist1 context it’s showing
WARNING[11886]: file.c:644 ast_openstream_full: File 0 does not exist in any format
knowing they both run the same agi file it’s streams normally in unlist but not unlist1 what might be causing this issue
