Buenas noches, acabo de instalar asterisk 22 y freepbx 17. Tengo un problema con las llamadas entrantes, las salientes funcionan bien. El problema es que me aparece este error ERROR[1289][C-00000002]: pbx_functions.c:650 ast_func_read2: Function SIP_HEADER not registered y no se como solventarlo. ALguna ayuda?
I ran into a similar SIP header issue on FreePBX where the custom headers weren’t passing correctly. Turned out I needed to adjust the pjsip_custom.conf and reload the config. Also, make sure your trunk provider supports the headers you’re sending. Sometimes using a pre-dial hook or setting variables in extensions_custom.conf does the trick. Debug logs were key to solving it.
