Cisco Book store gives information about all required books for CCVP. There is a book "Cisco IP Telephony (CIPT) (Authorized Self-Study), 2nd Edition" which is for CCM 4.x. But, could not find any book for CCM 5.0. Could you please let me know, which book I should refer for CCM5.0 and if it is there in the list of CCVP books(i may have overlooked it). It would be great if you could tell me the books that are available in Safari Online.
