I run call call manager V4.0 with English at the moment, we are going to add 60+ IPT extension for a new plant in Japan. How to add additional language support (i.e. display japanese name/softkey at IPT phone) in the existing call manager servers? When a IPT extension (with Japanese calling party)calls out to a English ipt extension, Does it display Japanese or English. Do I need to procure Japanese license/software to support dual languages in Call manager?
