Configuring Cisco AXL sync

Follow the steps below to configure TIM Plus to perform directory synchronisation with your Cisco UCME:

1. Click on the Directory tab.
2. Choose the site you want to configure and click Properties.
3. In the Site Properties window, select the Sync tab.
4. Tick the option entitled Synchronise with the following device .
   
   
5. In the Host field, enter the IP address of your UCME.
6. In the Port field, enter the port number of the IOS service, e.g. 23 .
7. In the Username field, enter the username of the IOS login that can perform synchronisation.
8. Click on the Set button and enter the password of the IOS login that can perform synchronisation.
9. Click on the Save button to apply the changes.

Configuring UCME to send RADIUS events

Use Telnet to connect to the IP address of your UCME as shown below:

Single site configuration

Enter the following commands to enable the UCME to send RADIUS events to TIM Plus:

Multi-site configuration

To configure a multi-site system, follow the steps below:

Replace SITE_NAME with a unique name for the destination RADIUS information. Replace SITE_IP with the IP address of the RADIUS server. Replace SITE_KEY with the secret you want to assign to that specific site.

Step	IOS Commands	Description
1	enable	Causes the UCME to enter EXEC mode. Type your EXEC password if requested
2	conf t	Enters the global configuration mode
3	aaa new-model	Enables aaa accounting mode
4	aaa accounting update newinfo
5	radius-server vsa send accounting	Enables VSA events
6	gw-accounting aaa	Enables aaa accounting
	acct-template callhistory-detail
	exit
7	radius server SITE_NAME	Configures the call accounting for each separate site
	address ipv4 SITE_IP acct-port 1612	Specifies the IP address and port of TIM Plus's RADIUS, to which CDR data will be sent, e.g. 192.168.0.1:1612
	key SITE_KEY	Specifies a RADIUS authentication secret that will be used by TIM Plus (configured in the next section), e.g. C1sco
	exit	Exits current site configuration
Repeat step 7 for each individual site
8	aaa group server radius SITE_NAME	Configures a specified aaa server group
	server name SITE_NAME	Specifies a RADIUS server to use for this aaa group
	exit	Exits current site configuration
Repeat step 8 for each individual site
9	aaa accounting connection h323	Configures the aaa connection information
	action-type start-stop	Setting the action type will send RADIUS information when the call starts and stops
	broadcast	Enabling broadcast means that all the aaa groups will be sent RADIUS data
10	group SITE_NAME	Specifies the aaa group(s) that the accounting system will send RADIUS data to
Repeat step 10 for each system
11	end	Exits configuration mode
12	wr	Saves the changes

For a system with five or more RADIUS servers, it is recommended to amend the server retransmit options in the UCME, in order to reduce the stress on the phone system.

IP radius source-interface

To force RADIUS to use the IP address of a specified interface for all outgoing RADIUS packets, use the ip radius source-interface command in global configuration mode.

ip radius source-interface SUBINTERFACE-NAME

 If you don't wish to use the IP address of a specified interface, use the no form of this command.

no ip radius source-interface

Configuring TIM Plus to capture RADIUS packets

Follow the steps below to configure TIM Plus to receive RADIUS data from your UCME:
