You need an FXS port and a "PBX / intercom interface box".

The latter can be bought online or in telecom supplies store.


The product is for intercom, right??  Can I use that to buzz the door open by pushing the button on the phone???

Here is the situation, there is a glass door at our department, so we can see the people stand outside.  I just want to something to intergrate with our CUCM 6.12 (Skinny, NOT SIP), so we can push a button at the IP Phone to open the door.

Hi Ken,

No worries my friend

The C-1000b won't work on it's own. Wouldn't you want to be able

to check who is @ the door via the Intercom first before buzzing them in?

If this is a locked door, then it must be for a reason. The whole concept

is based on an active phone call between the door and the respective IP phone

and then using DTMF to activate the door stricker mechanism to unlock

the door. If you don't use an Intercom then there will be no way to intiate a call

to the IP phone to start the process.



The door is a glass door and the visitors already through security checkpoint, so they just dont want to walk to the door and open it.

They just want to open the door without getting up.

Well, if those two products have to work together, then thats fine.  I am just wondering if there is door buzz feature without intercom module.

Hello Rob,

       I have the exact setup like what you mentioned above.  I have a W3000 and C-1000B.   I was told by Viking that I cannot set up an ATA with this device because the ATA will not work with W3000.  In addition, they told me I need a FXO and not an FXS.  I have the FXO.   Can you give me some directions on how to configure the ATA to work with the equipment above?  Thanks in advance.

I'm in the exact situation, were you able to find a solution ? if you did could you provide me with the product you chose and how it working ?

I had to use a FXO card to interface with the Viking C-1000B and W3000 Door Buzzer.

On the router with FXO card:

voice-port 0/1/0

connection plar 1100 <==number to ring when someone buzzes in.

description Door Buzzer

station-id Door Buzzer

voice-port 0/1/1

dial-peer voice 1 pots

port 0/1/0

dial-peer voice 2 voip

destination-pattern 1100

session target ipv4: <== your call manager

codec g711ulaw

interface GigabitEthernet0/0

description LAN Interface

ip address

no ip redirects

no ip unreachables

no ip proxy-arp

ip pim sparse-dense-mode

ip virtual-reassembly in

load-interval 30

duplex auto

speed auto

no mop enabled

h323-gateway voip bind srcaddr

Create a H323 Bind on your router:

interface GigabitEthernet0/0
     h323-gateway voip bind srcaddr <== router IP

Create H.323 gateway on call manager and point to the router

Then if you need to transfer it to a DN that is being manned, create a partition, CSS and translation..

Hope this helps.

Could you help me set up a Call Manager Express 

I have 
1 W-1000-EWP (connected to an FXS port) 
1 RC-24 

I want to do this. 

Pressing the button on the intercom (W-1000-EWP) ringing all, would like a ring that someone is at the door IP phones. 

Reply from any IP phone by dialing the extension 36 to the intercom 

Open the door with the extension 6 

For this requirement did the following: 

I did a HUNT-GROUP in parallel mode and assign all extensions 
a pilot number 601 
When I put a FXS port coonnection-plar 601 
601 pilot number assigned to all extensions as a secondary extension 

But I have not been successful because only sounds the phone every time I press the call button of the intercom. 

Annex part of the configuration: 

In the FXS port where I connect the intercom viking

voice-port 0/0/3

cptone MX

connection plar 601

description conexion del intercom

station-id name intercom

 station-id number 36

caller-id enable

number 20 secondary 601

pickup-group 1

label YOYIS 20

description yoyis

dial-peer voice 10 pots

destination-pattern 36

port 0/0/3


I'm doing wrong?
