Cisco Unified Communications Manager to automatically
assign directory numbers to new phones when you plug those phones in to your
enabled on secure mode now. This enhancement provides greater security for your
system because you can secure your cluster while provisioning new phones. It
also simplifies the registration process because you don't have to disable
cluster security to register new phones.
If you create a
device pool that allows only 911 (emergency) and 0 (operator) calls, you can
use that to prevent unauthorized endpoints from connecting to your network when
autoregistration is enabled. New endpoints can register to this pool, but their
access is limited. Unauthorized access by rogue devices that continuously boot
in and attempt to register to your network is prevented. You can move a phone
that has auto-registered to a new location and assign it to a different device
pool without affecting its directory number.
The system doesn't
know whether the new phones that are auto-registering are running SIP or SCCP,
so you must specify this when you enable autoregistration. Devices that support
both SIP and SCCP (such as Cisco Unified IP Phones 7911, 7940,
7941, 7960, 7961) auto-register with the protocol that is
specified in the enterprise parameter called Auto Registration Phone Protocol.
support only a single protocol will auto-register with that protocol. The Auto
Registration Phone Protocol setting is ignored. For example, any Cisco Unified
IP Phones that support SCCP only will autoregister with SCCP even if the Auto Registration Phone Protocol
parameter is set to SIP.
We recommend that
you use autoregistration to add fewer than 100 phones to your network. To add
more than 100 phones, use the Bulk Administration Tool (BAT). For more
