IP Phones

Hot Applications For IP Phones

BY STEFAN KARAPETKOV

The makers and distributors of IP telephones have worked very hard to convince their customers that an IP phone is a real telephone, and not merely an inspired piece of geekery. They�ve succeeded. Now what?

It�s time to understand that, while an IP telephone is a real telephone, it�s a different kind of telephone, and can be used to retrieve and distribute information in new ways. So it is with technology. The personal computer is a real word processor, but we now do much more with personal computers than process words.

What might we do with this new, powerful, flexible information appliance?

The applications we have in mind are anchored in an enterprise IP network connected to the Internet. Such networks are growing in corporations, government agencies, and educational institutions. The telephones we have in mind range from basic desk sets with limited displays to sets with some graphic display capability. In any case, an IP telephone is not a PC, so the information we envision sending and receiving is relatively brief.

That said, let�s use our imaginations.

In a corporate environment, there are many pieces of information, which the corporation sends to its employees using methods that now range from ineffective to inconvenient to nerve shattering.

Imagine that Worldwide Widgets needs to inform its employees that the enrollment period for company health insurance ends next Monday. The human resources department might distribute a desk-to-desk paper announcement for its employees to lose or ignore. It might send an e-mail for them to delete or ignore. It might even place itself and its employees at the mercy of the United States Postal Service. Or, the HR people might make one of those wake-the-dead public announcements over the public address system, which, while hard to ignore, are extremely irritating.

A short, text-based message like this one, however, might be displayed each day on the screen of a modestly capable IP phone. In the case of Worldwide Widgets� insurance enrollment deadline, the message would be a single, simple, declarative sentence: �The deadline for benefits enrollment is Monday, October 30.� Employees would see this message every time they looked at their phones. They couldn�t lose it or delete it. They could ignore it, but ignoring this message would require more effort than remembering it. Irritation would be minimal.

In the lobbies of its buildings, Worldwide Widgets might use IP phones with displays to deliver messages to visitors. The company might warn delivery drivers that, due to parking lot repairs, freight deliveries will be received at a different door than usual, starting next Monday. It might tell a limousine driver, arriving to pick up executives for trips to the airport, that his passenger is on his way down -- and of course, it might use the same capability to let the executive know his ride has arrived.

In its warehouses or factories, Worldwide Widgets might use some of the more powerful IP phones to push the latest inventory or production information down to managers, who could adjust their activities accordingly.

Finally, the operator of a corporate IP network might use the company�s IP phones to send information to selected employees -- the number of calls received in a company�s call centers, updated hourly, to certain marketing executives, for instance.

These are �push� applications for IP telephony. As is always the case in sending information, the trick is to know what kind of information to send and which to save for some other medium. Any information that is ambiguous, or requires interpretation, or cannot be parsed in simple sentences, is probably better sent by other media. Those of us who labor in cube farms can be grateful that the size of IP phones� display screens will force corporations to think before they communicate, and then communicate clearly. Of course, even short, concise messages might not be appropriate for IP phones. A company might want to use other media to tell its employees their building is on fire, for example.

What can be pushed can also be pulled. Consider the limo driver who arrives at Worldwide Widgets to read, on an IP display phone, that his passenger is delayed. He might manipulate the keys to tell his passenger�s secretary that he will wait in the car, and ask the passenger to ring his cell phone when he�s ready.

Consider also the visitor who reads the stock quotes on the IP display phone in the lobby. He or she might be allowed to manipulate the display and view the information differently -- a graphic representation of the week�s quotes, for example.

Even Worldwide Widget�s human resources information, pushed down to desktop IP phones in the cube farm, can be pulled. An employee who has a question and wants an actual human to answer it for him might be prompted to press a button to let HR know he�d appreciate a call. Employees might also ask simple, yes-or-no questions: When is the deadline to enroll for health benefits? In practice, a system might be programmed to understand a shorthand version of such a question: Benefits deadline? And the answer would come back: Oct. 30.

Some of the hottest applications for IP phones are based on instant messaging and presence, the new technologies promising to solve the annoying �phone tag� problem. Instead of trying to reach a person via different phone numbers and e-mail, the IP phone user can monitor the status (presence) of a person, and respectively decide the best way to reach him or her. Users can make one of the IP telephone�s keys their �presence key.� By pressing this key, they can select their status, e.g., available; unavailable for voice call but available for instant messaging; reachable on his cell phone; and so on, and let a group of regular communication partners, or the whole world if necessary, know that. To simplify the management and monitoring of contacts (sometimes called buddies), the desktop IP phone might also store buddy lists, and the user might use those lists to place voice calls or to send or receive short instant messages: �I�m busy.� or �Call my cell phone.� While some of this functionality may be delivered on a standard two-line display phone, large-screen IP phones are more convenient as users would be able to see longer messages and entire lists of contacts/buddies. Information input is also easier since users could use a stylus to �type� on a virtual keyboard displayed on the phone�s large screen.

Vertical markets are full of push/pull possibilities.

For example, many schools have telephones in their classrooms now, and many also have computers. A teacher often uploads his or her attendance information by computer, or by calling the office. As any teacher will confirm, there is no convenient time to do this. The teacher must log onto the computer network, or dial the office. It might be easier, given an IP phone in each classroom, for the teacher to press an �all present� or �not all present� button on the phone. The latter message would trigger a class roster, and the teacher could scroll down that roster and mark the names of the absent students. Alternatively, the teacher might be asked to spell out the last names of the absent students. That takes a little longer, but not as long as waiting or someone to answer the phone or waiting for the right screen to come up on the computer.

The hospitality industry is rich with possibilities, too. As any road warrior knows, many hotels offer �express checkout� options through their in-room television sets. It might be quicker and easier for a final bill to be pushed to a hotel room IP phone -- a phone with relatively powerful display possibilities -- so that the customer could answer yes or no with one stroke, and check out. Other announcements, such as �room service ends in one hour,� might be pushed down to the customer.

So IP phones are real phones, and their potential for spreading information more efficiently is equally real.

Rolling Out The IP Phone

BY IAIN MILNES

Rolling out IP phones used to be a time consuming task. Administrators had to manually configure each phone by determining its IP address and then logging into a Web-based page hosted on the phone. From there, the administrator needed to fill in all necessary information to configure the phone for operation within the network.

Luckily, there is now a de facto standard method that makes the deployment of IP phones much less cumbersome. System administrators no longer need to fret at the prospect of deploying an IP phone system. Who wouldn�t appreciate the ability of taking an IP phone out to the box, scanning its MAC address into administration software, and then immediately have it boot up completely configured and ready for making and receiving calls? Using a TFTP server, possibly in conjunction with DNS SRV (see RFC 3263), IP phones can be easily deployed in minutes rather than the hours or days that it used to take.

With the TFTP approach, a configuration file is created on a TFTP site that the phone accesses. The administrator takes the new phone, records its MAC address, and creates a file named <MAC Address>.cfg. The administrator then moves this file onto the TFTP site. The address of that TFTP site may be internal or external to the IP phone system, and the file is usually placed in a subdirectory. A global file specifies the subdirectory where the individual phone files are located. The file may contain other information common to all phones, but the minimum requirement is that it specifies where a phone can get its unique configuration file. Many IP phone systems today, create these configuration files automatically and act as the TFTP server.

When the phone powers up, it uses DHCP to obtain its IP address. In the response, it also obtains the name of the domain to which it is connected and the address (or fully qualified domain name, also known as FQDN) of the TFTP server. The phone reads the global file on the TFTP server and finds the name of the subdirectory where the unique configuration file is located. It then reads the unique configuration file, which specifies the address of the SIP registrar. The phone then registers with the registrar using:

<SIP Address>@<domain name>

In the case where IP phones don�t support TFTP auto-configuration, or the configuration file only specifies the domain name for the registrar, the phone uses DNS SRV to find the registrar�s address. When the phone obtains its IP address through the DHCP server, it also receives the address of one or more DNS servers. It sends a query to a DNS server for the address of the SIP server. This is a specific record query of the form:

_sip._<protocol>.<domain>

where the protocol is normally TCP, TLS, or UDP. This entry needs to be configured on the DNS server, so that it responds with the address of the SIP registrar. The phone then registers with the SIP registrar.

The configuration files on the TFTP server are usually stored in text format (so you can read them) and they can contain a lot of data. For example, the file can specify which software version to use, so that automatic updates of the phone can be performed. The file can specify preferences determined by the administrator such as which language to use or which ring tones to use.

When evaluating the IP phone that best suits their organization, IT managers should consider whether or not the phone supports auto configuration using TFTP, DNS SRV, or both. How well the deployment of IP phones is streamlined can greatly affect the ease of deployment and maintenance of an IP phone system. The more automated the procedure is, the better.
