0
Enables or disables callback security. When callback security is
enabled, phone number memory locations 0–4, used for quick
dialing and DTR dialing, become unavailable and are replaced by
callback security memory locations 1–30. The phone number
memory locations and their contents are restored when callback
security is disabled.
#DB0 Disables callback security.
#DB1 Enables callback security.
#CBNy=[-]x Store Callback Number

Stores the callback dialing string x in memory location y. The
dialing string can include the digits 0 through 9 and any of the
following characters: #, *, comma (,), semicolon (;), W, A, B, C, and
D. Up to 30 characters can be used. Example:
AT#CBN01=9,16127853000. If the optional - character precedes
the dialing string, and the caller appends the same character to the
password, the caller is connected immediately, and the hangup
and callback are skipped.
