Scenario:
You have a Cisco Unified Communications Manager (CUCM) system and want to configure a SPA112
analog telephone adaptor (ATA) to register to the CUCM so that you can use up to two analog phones or
similar FXS devices with the CUCM.
Overview:
In this application note, I have a Cisco Business Edition 6000 (informally also known as the BE6000 or
BE6k). My BE6000 is running CUCM 9.0.1.10000-37.
I have a SPA112 ATA running 1.3.1(003) firmware and an analog phone connected to the PHONE 1 port
of the SPA112.
- The CUCM has a 4-digit internal dial plan starting with 1.
- The CUCM is already configured and has other users and phones configured and able to make
calls with each other.
- The SPA112 ATA is starting from a factory defaulted state.
Configuring the CUCM
Configuring the CUCM is a discipline unto itself. This is why folk work so hard at acquiring their CCIE
Voice certification. This application note does not address important topics such as security and optimal
configuration which are mandatory for live deployment.
These instructions must be considered to be for internal and secure lab-use proof-of-concept only.
Overview
The following CUCM administration tasks to prepare the CUCM for connecting a SPA112 are described in
detail:
- Define a CUCM user that will be associated with the SPA112 Line1
- Define a third-party SIP phone for the SPA112 Line1
- Associate a Line / DN (directory number) to the previously defined SPA112 Line1 third-party SIP
device
- Associate the SPA112 Line1 user with the SPA112 Line1 third-party SIP device.
Detailed Instructions
- In this subtask, you define a user called 1022 to associate with Line1 of the SPA112. The 1022
user name is configured with a password of 1234, a PIN of 1234, and Digest Credentials of 1234
a. Navigate to User Management > End User > Add New and complete the form
appropriately based on your CUCM deployment:
