The presence of Call emission in the red spectra of AGN is now commonly observed. A sample of forty AGN has been surveyed by Persson (1988): fourteen of his objects show a clear emission of the Call triplet at 8498, 8542, 8662A (CaIIT) with a strength correlated with that of the optical Fell emission. The study of the Call triplet puts new constraints to the physical conditions in the low ionisation region of the BLR.
