UCM6304a synchronise contacts with GRP26xx phones


I have a UCM6304a, I filled in the “EXTERNAL CONTACT” part with some entries, and I would like to know how to synchronize with the GRP26xx devices?

knowing that by using WAVE, the names of my contacts appear in incoming calls.

thanks in advance.


try using the UCM LDAP address book


Thanks a lot
I followed your advice and also the grandstream guide
the directory is synchronized on my devices
