exten => _.,n,Set(ME_1=${CUT(MESSAGE(from),< ,2)})
exten => _.,n,Set(ACTUALFROM=${CUT(ME_1,@,1)})
exten => _.,n,MessageSend(${ACTUALFROM},ServiceCenter)
exten => _.,n,Hangup()
exten => _.,n,Hangup()
i have this error into asterisk cli:
res_pjsip_header_funcs.c:520 func_write_header: This function requires a PJSIP channel.
this happens when it executes: exten => _.,n,Set(PJSIP_HEADER(add,X-IM-received)=${EPOCH})
how can i add a new header correctly please?
