Configure
the Maximum Number of Phones Allowed to Register.
Before an
IP phone can register with CUCME, you'll need to set the maximum number allowed
to register to CUCME.
The max
limit depends on the router platform and the higher the router model,
the more
IP phones CUCME will support. Note that each reservation consumes
router's Digital Signaling Processor (DSP) resources and license
purchased.

Establish
the Maximum Number of Directory Numbers (Phone Numbers)
Before an
IP phone can register with CUCME, you'll need to set the maximum number of
directory numbers (DN). The
maxmimum number of supported DN depends on the router model and it also consume
router resources.

Set the
IP Address Used by CUCME
Before an
IP phone can register, CUCME needs an IP address used to receive requests and
respond to IP phones.
CUCME
uses TCP port 2000 by defaut, but it can be changed with the port option.
Any valid
IP address can be used on the Voice Router, but it's recommended to use either
the Voice VLAN subinterface or a Loopback address since it's always up.

Create
the Default Template Files
Newer
CUCME versions will automatically create the default template files for the IP
phone. In older
CUCME versions, You'll need to manually create the template files. Notice
the SCCP (Skinny Client Control Protocol) phone registration is rejected in
CUCME due to a clock syncrhonization issue.

Configuring
Directory Numbers (DN)
Ephone-dns
can be single-line, dual-line or octo-line (as of CUCME 4.1). This is
the number of simultaneous audio channels (lines) usable per phone button. For
example, call waiting and call transfer will need two audio channels: one
channel for the original caller and another to establish the third party
connection. Most IP
phones will use dual-line dns.

Create an
Ephone and Assign the MAC Address of the IP phone
CUCME
uses the ephone to connect directory numbers (ephone-dns) to the MAC address of
the IP phone. Three
common ways to get the MAC address of an IP phone:
1. From
the box of the IP phone (sticker lable with bar codes)
2. At the
back of the IP phone
3. From
the LCD screen of the IP phone: press Settings > Network Settings.
Get the
MAC address from the Switch MAC address table or from the DHCP pool binding in
the Voice Router.

This is a packet capture wherein an IP phone (x2002) establishes an SCCP connection to CUCME (10.15.0.1) to route a call to x2001.
The two IP phones established a direct Real-time Transport Protocol (RTP) connection afterwards.
