Huawei AR Series: PBX Number Parameters

Huawei AR Series: PBX Number Parameters

Comments 0 Comment

When deploying Huawei AR Series Routers to act as an IP PBX, you may need some extra parameters according to your environment. The pbx number-parameter command in Huawei AR routers sets control points for a PBX.

You can apply these parameters in voice view menu, and the number parameter usage format is like below:

pbx number-parameter name value

Here name specifies the name of a control point and the value is an integer that ranges from 0 to 249. Value specifies the value of a control point and is an integer that ranges from 0 to 4294967295.

Since the notation is not easy-readable, you can use the table below for parameters and values:

Asterisk & FreePBX: How To Create AMI User?

Asterisk & FreePBX: How To Create AMI User?

Comments 0 Comment

AMI (Asterisk Management Interface) is used for third party applications to work properly with Asterisk (FreePBX). Applications can retrieve updated information about system events via AMI and send some commands to Asterisk.

To use AMI on Asterisk and FreePBX, you need to define a user and password. You can create this in two ways:

  1. By editing the /etc/asterisk/manager.conf file
  2. By creating a user with Asterisk Manager in FreePBX.

Let’s examine both methods in more detail.

Creating an AMI User on Asterisk:

  1. Connect to the Asterisk server via SSH.
  2. Open the /etc/asterisk/manager.conf file with an editor.
nano /etc/asterisk/manager.conf
  1. Enter the AMI settings in the [general] section:
[general] 
enabled = yes 
port = 5038 
bindaddr = 0.0.0.0 
displayconnects = no
  1. Create a new user under the [general] section:
[amiuser] 
secret = 123456 
deny = 0.0.0.0/0.0.0.0 
permit = 192.168.0.0/255.255.255.0 
read = system,call,log,verbose,command,agent,user,config,command,dtmf,reporting,cdr,dialplan,originate,message 
write = system,call,log,verbose,command,agent,user,config,command,dtmf,reporting,cdr,dialplan,originate,message 
writetimeout = 5000

Note: In this example, the username is amiuser and the password is 123456. It only accepts requests from the 192.168.0.0/24 network, but all access is read and write.

  1. Save and close the file.
  2. Reinstall the Asterisk Manager module:
asterisk -rx "manager reload"

Creating AMI User on FreePBX:

  1. Click Settings in the top navigation bar and then Asterisk Manager Users:
Asterisk Manager Users
Asterisk Manager Users Menu

2. Click the Add Manager button to add a new user.

FreePBX Add Manager
FreePBX Add Manager

3. Here you can see the settings window for a new user. Complete the relevant fields here:

AMI User Properties
AMI User Properties
  • Manager Name: Enter the AMI Username (no spaces).
  • Manager Secret: Enter the password for the AMI User.
  • Deny: Here you can specify the IP address and subnet mask that you want to restrict connection with AMI. You can use the “&” symbol to specify multiple networks, eg 192.168.1.0/255.255.255.0&192.168.2.0/255.255.255.0
  • Permit: Specify the network or unique IP address to which you allow AMI connection.
  • Write Timeout: Enter the timeout period for the execution of the AMI command.
  1. Set access permissions using the Permissions tab.
Asterisk Manager Users
AMI Permissions

5. Click the Submit button at the bottom right to save the settings and then click Apply Config appears at the top left to complete the process.

How to Enable CDR & CMR on CUCM

How to Enable CDR & CMR on CUCM

Comments 0 Comment

The Call Detail Records (CDR) and Call Measurement Records (CMR,  also referred as “Call Diagnostics Records”) offer details for each phone call passing by the Cisco Unified Communications Manager (CUCM). In CUCM CDR CMR records are disabled by default, so that you have to enable them manually.

You can enable CDR and CMR in CUCM by following steps below:

How to Enable Call Detail Record (CDR) on CUCM:

  1. Login to administration page on Publisher CUCM. Click System -> Service Parameters menu.

2. Then select your server which has callmanager service enabled and then select Cisco CallManager (Active)

3. On System section find CDR Enabled Flag Parameter and set to True. If you’d like to see calls with zero duration, find CDR Log Calls with Zero Duration Flag (just below the CDR Enabled Flag)and set to True.

4. Do this for each CUCM Server if you have more than one server that has Callmanager service enabled.

How to Enable Call Measurement (CMR) on CUCM:

  1. On the same Service Parameter menu, go up and click Advanced.

2. Find the Clusterwide Parameters section, and change Call Diagnostics Enabled Parameter from Disabled to which option you wish.  

Note: Since CMR parameter is in Clusterwide Parameters, you don’t need to enable this on each server.

How to Get Wireshark Capture in CMS?

Comments 0 Comment

In this article, you can find steps to get Wireshark Packet Capture over Cisco Meeting Server (CMS).

While dealing with Cisco Meeting Server (CMS), you may encounter many errors such as audio / video packet loss, signaling problems, and you may need to listen to network traffic from time to time to fix them. In this article, you can find steps to get Wireshark Packet Capture in Cisco Meeting Server (CMS).

CMS Wireshark Packet Capture Steps:

  • First, connect to your CMS server via SSH to access the CMS MMP interface.
  • In some installations, CMS may have more than one network interface. So, after connecting, use the callbridge command to find out which interface to capture from:
Find Interface Using “callbridge” Command

To start the packet capture process, use the pcap command (in our example we will use the pcap a command):

Starting Packet Capture with “pcap a” Command
  • Once you start the Packet Capture process, re-create the traffic you want to listen to, and then use the Ctrl + C key combination to finish the capture process.

Note: The size of the .pcap file can be up to 100MB.

  • You can use an SCP program to download the generated .pcap file (in our example we will use WinSCP). Connect to the CMS using the username and password that you SSH connection with the SCP program, and find the corresponding .pcap file, and then download it to your computer:
Accessing the pcap File with WinSCP

That’s all 🙂

Cisco multi-port voice gateways have one or more ports for analog phones which is called RJ-21. Since the distance between the Cisco voice gateway and the phone distribution frame can be variable, you may need to make a special cable to connect these ports.

You can see the RJ-21 port and pin order used in Cisco multi-port analog voice gateways in the following image:

In the table below, you can find the pin sequence of RJ-21 ports used in Cisco multi-port analog voice gateways:
