Cisco CUCM 9.1 Intercom: Indoor & Outdoor IP Door Phones

Cisco as you know (hopefully) is a huge technology giant. They turn over close to 50 billion dollars. They manufacture a variety of networking hardware. One product not in their own product portfolio, are Cisco IP intercoms. A network based door phone that can integrate to the Cisco IP telephony system.

Here at “The Endpoint Warehouse” we are receiving more and more enquiries from Cisco partners. Asking can we help and supply a Cisco CUCM 9.1 Intercom. One that can be installed at a internal door or external barrier.

The Cisco door phone we provide works great with CUCM 9.1. Having passed interoperability testing some years ago, it actually works with many older versions too. You can see the product we distribute here (on the Cisco website). Its been live in the Cisco product catalogue for a number of years.

Today we are going to show you how easy it is to set this system up. We are going to show you how the Cisco door phone compares to other SIP and VoIP solutions. In particular we are going to look at Commend who make VoIP intercom systems. We will also take a look at ALGO and show you how our  Cisco CUCM 9.1 Intercom system is the easiest and fastest to set up.

We are going to explain how fail-over support works and how the Cisco IP intercom back ups to the main Cisco Unified Communications server.

The Single most greatest feature of our product, is the set up. Our cisco partners and customers say its the easiest system the have ever installed. Less time on door and secure entry, frees your time up for other aspects of the installation.

Anything that is fast and easy to install, is a good addition to your own portfolio. If customer A, offers a phone system and door entry included. If customer B, does not. The bid/quotation with the bundled solution, may have a slight advantage.

How other Cisco IP Intercom Systems set up

ALGO manufacturer a SIP Intercom solution. This IP based intercom system needs several parts for the installation. Like a lot of “SIP” door entry systems. This device is “SIP compliant”. If SIP technology is new to you, check out this external page on: “What is SIP”.

CyberData Corporation, who we distribute for, their secure entry range has direct certification from Cisco. There is a long and established working relationship, with CyberData and Cisco. They have a very strong alliance. Furthermore, Cisco have allowed CyberData to embedded certain fail-over features within the system. There is no other door entry system that can offer the fail-over support that our CyberData system offer.

The Algo door phone needs quite a few parts to complete the install. It also needs a 230V power supply. You also need twisted pair wire. The functionalities are pretty much the same as CyberData. However, the CyberData Cisco certified ip intercom needs no other parts.

Lets take a look at CyberData

Where as Algo and others, like Aiphone for example, need several parts. Cyberdata ONLY needs a POE switch and broadband connectivity. You could plug the Cisco intercom directly into your Cisco Power Over Ethernet switch. This completes the hardware installation.

Make use of technology that is already installed 

  1. You need a broadband connection – Everywhere has the internet. Or at-least, the Cisco architecture you are installing within, will have the Internet. This system part has already been installed.
  2. You need Power Over Ethernet – The Cisco SIP door phone is PoE 802.3af enabled. One data cable back to a Power Over Ethernet switch is all you need ! POE switches are usually installed. This saves you the job 🙂
  3. Cisco Call Manager Server / SIP-Server – If you need a Cisco door phone, usually your Cisco telephony network is in place. Register the device to the Call Manager Server. Your door phone is now part of the telephone system.
  4. The Cisco intercom has an integrated dry relay contact – You can use this to open doors gates and barrier.
  5. IP and Mobile Phones – Just like everything else, Cisco IP phones are in place and people have mobiles. The door phone can dial and speed dial these telephone endpoints. This is another cost saving as most other entry systems need tied in handsets.

 Fail-over and redundancy Support

If we take a look at Commed. Their cisco door entry system requires several parts. Commend does not feature embedded fail-over support. The CyberData Outdoor and Indoor SIP door phones feature SRST. Survivable Remote Site Telephony is Cisco’s own backup feature for remote sites.

Cisco have allowed CyberData to integrate this backup feature within their range of SIP enabled IP endpoints.

Commend and other secure entry systems need a separate server on-site. This is used for backup support. Additional servers cost money and also cost time on installation.

CyberData backs directly up to the centralised Cisco Call Manager Server. This is currently running at 9.1+. Cyberdata also integrates to much older versions. If you had say, a IP intercom installed at the main site. The CyberData door phone would register directly to this. The server would offer the support to the endpoint

For remote locations that are too small to demand a Cisco Server, these endpoints would use SRST and backup to the centralised Cisco Server. This external page explains Cisco SRST very well.

If your cisco door entry application is at the main or even a remote site, you will not need any additional servers. This makes the installation much easier and quicker to complete.

DTMF controlled Relay

When we first started in VoIP we didn’t really know what DTMF was. All CyberData devices (SIP Speakers/SIP Notification/SIP Secure Entry) feature an integrated dry relay contact. This is like an I/O board that sits on the PCB board. This is DTMF controlled. DTMF are the signals our phones send when we press a button. When you call Sky or BT, their IVR menu knows how to route the call through DTMF (Dual Tone Multi Frequency).

[mk_image src=”http://endpointwarehouse.com/wp-content/uploads/Cisco_CUCM_9.1_Intercom_systems.jpg” image_width=”300″ image_height=”300″ crop=”true” hover=”true” align=”left” margin_bottom=”10″]

The dry relay contact features NO (Normally Open) contacts. If you are installing the single call button outdoor barrier phone, or the outdoor keypad option. You can wire the N/O contacts direct to the gate or barriers controller unit.

For outdoor and internal door entry points, you would usually have an external relay (with its own power supply). This high powered device triggers the door lock. The dry relay contact on the PCB board, triggers the external door relay.

How do we trigger the relay ?

Through the door phones web-page settings, you set up a “DTMF relay code”. This can be up to 25 digits long. For this example let’s use, 0192572. You won’t know what that relates to, but it’s one we can easily remember :-). The door phone places a call to a Cisco IP Phone or Mobile phone. If the person who answers the call wants to grant access, they hit “0192572” into their keypad.
Practically all IP phones and our mobiles send DTMF in out of band via RFC2833. This is the standard supported and adapted protocol from DTMF delivery. Intercoms like Paxton use SIP INFO, which is not supported. That’s why Paxton (and others) need special apps on phones. CyberData does not. This further adds to its effortless and easy set up. 3CX have this very useful page on all things DTMF.

To recap. There are many IP intercoms on the market that say they are SIP solutions. Most are only SIP compliant. Our CyberData SIP secure entry phones are certified directly by Cisco. They have been for a number of years.

Furthermore, CyberData needs no other system hardware parts. Other entry systems need tied in handsets and additional servers. Other manufacturers sell additional parts that make the system work. With CyberData you can certainly save some time and money.
Finally, our devices have embedded failover support. This is an excellent point to make. It makes your system even quicker to set up ( no addtional servers). Also, just the fact Cisco have allowed Cyberdata to program these features within their configuration settings.
