[Aqualion (Stanislav)]

Good day!
Can You advise how to solve problem?
Template ​​does not load into the phone these values:

LDAP Number Filter LDAP name filter is the filter used for name look ups. Please refer to user manual for examples String

P8025 = (&(!(userAccountControl:1.2.840.113556.1.4.803:=2))(telephoneNumber=%))

LDAP Name Filter LDAP name filter is the filter used for name look ups. Please refer to user manual for examples String

P8026 = (&(|(cn=%)(description=%))(!(userAccountControl:1.2.840.113556.1.4.803:=2))(telephoneNumber=*))

LDAP Display Name. The entry information to be shown on phone LCD. Grandstream phones will display up to 3 fields String

P8030 = %cn %telephoneNumber

Perhaps, problem with symbols ‘&’ and ‘%’ ?
