goog evening - BOA NOITE
Hi - OLÁ

common thing to say is " Lisboa approach, BOA TARDE ( if afternoon, otherwise one of the others)
and then proceed as usual
when leaving the freq. make all your comms. and in the end just before your callsign ADEUS, BOA TARDE ( or one of the others)
" ............. thank you ( obrigado) ADEUS ,BOA TARDE"
