Cisco Small Business phones (the SPA-3xx and SPA-5xx ranges) support central address books using LDAP.

The settings are notoriously difficult for people unfamiliar with LDAP to get right. Here is my example using an OpenLDAP server:

So in my LDAP tree I'm using sn for surname and cn for first name.

Set up with Microsoft Active Directory shouldn't be too much different from this but the exact settings will just depend on your AD structure.

In my Previous blogpost, I explained how to connect a digital keypad with ProTalk door unit. That was entertaining was is`nt :). Now lets add a push button to the previous scenario to make things more exciting.

The blogpost will go through the process of attaching all three components together. Each module comes with separate connection cables that can be found in packaging. You should have following cables with each module.

a. Audio/Video module:

>> 1 x 8 pin connector (CC8)

b. Digital Keypad:

>> 1 x 5 pin connector (CC5)
>> 1 x 3 pin connector (CC3)

c. Push Button:

>> 1 x 3 pin connector (CC3)


Lets start connecting these components step by
step.

1. Connect CC8 cable to 8 pin connector on Audio Video module.

2. Connect one end of CC5 to Output(CN2) and one end of CC3 cable to Input(CN1) connector on the keypad.

3. Connect CC3 cable to the Input(CN1) on the push button.

If everything is connected correctly, it should look something like this.

Now lets move forward to last few step.

4. Connect other end of CC3 cable connected to push button to LT(3 pin) connector on A/V module.

5. Connect second end of CC5 cable from keypad to EXP(5 pin) connector on the A/V module and CC3 cable to the Output(CN2) on the push button

6. Finally, last step is to connect the CC8 cable to the push button. One thing to keep in mind is, each cable from the 8 equate to "key 3-10" on the web interface. i.e.

black = 3rd pushbutton
orange = 4th pushbutton
green = 5th pushbutton
white = 6th pushbutton
red = 7th pushbutton
yellow = 8th pushbutton
brown = 9th pushbutton
blue = 10th pushbutton

Since our scenario just has one push button in place, I need only one out of 8 cables i.e. Black. So last step is to plug the stripped end of the black cable to the green screw terminal block on the push button.

Now log on to the web interface of the door unit and configure the unit to get things started.

Recently, we have successfully completed interop testing of the ProTalk SIP door unit with Broadsoft platform(not broadsoft certified).

Here is a quick how-to guide to configure ProTalk SIP door unit with Broadsoft Server.

Firstly, the firmware on the door unit has to be on VoIP version: 1.99.2. To check the firmware version, web browse to door unit and click on Service page.

Then set the device as follows:

• SIP Proxy Server Address : as.broadsoft.com (provided by server provider)
  
  
• SIP Proxy Server Port : 5060
  
  
• SIP Registrar Server Address : as.broadsoft.com (provided by server provider)
  
  
• SIP Registrar Server Port : 5060
  
  
• Outbound proxy Address : IP address of outbound proxy server(provided by server provider)
  
  
• Outbound proxy Port : 5060

Secondly, enter the user details. User name part is the only bit that is tricky. To get the username for door phone, look for "Line port" field under device configuration. Line port setting should be something like abc123_321@domain.co.uk. You only need to put name part of sip uri i.e. abc123_321 as username. Finally enter password and authentication password and press save changes to register the device. Click here to see a snapshot showing require Broadsoft server user details.

This should allow you to make and receive calls from Door unit.
