VoIP System

Page address: http://www.mnsu.edu/telecomm/cisco/training/faq/voipsystem.html

Why do I get a message, "Your call cannot be completed as dialed" when I call another campus number?

During the period when phones are being transitioned to the new phone system, the following rules apply:

  • Cisco phone to CISCO phone = 4 digits
  • Old phone to old phone = 4 digits
  • Cisco phone to old phone = 9+389+4 digits
  • Old phone to Cisco phone = 9+389+4 digits

Basic rule during transition:

If you get "Your call cannot be completeed as dialed" dial 9 + 389 + 4 digit campus number.

What is Voice-over IP (VoIP)?

VoIP, or IP Telephony, is a converged voice/data technology that uses the data network to carry voice (telephone) traffic.

Why the change?

There are numerous compelling reasons. The need to support advanced network applications and emerging technologies with converged technology has become a reality in the industry and, particularly, within the university community. This state-of-the-art system will enable Minnesota State University to build a strong foundation for the future. In order to meet the growing demands of the university community, our current data network requires major upgrading. We will provide a more cost effective infrastructure by incorporating the voice requirements into this new converged technology. Costs will be controlled as the number of lines leased through HickoryTech will be greatly reduced. By sharing a common infrastructure, voice and data cabling, phone move charges, phone installation charges, and long distance charges will also be lowered. The change will also give us the ability to manage our phone system, enabling us to have access to more features and more applications (i.e., employees will be able to configure various features, such as speed dial, directly on the phone. They will also have the ability to program other changes, such as call forwarding, on the web). The upgrade to our computer network will allow for more reliability, improved security, and improved performance.

How much will these new phones cost and how should my department budget for this?

The overall plan is to replace all phones with a like-phone at no cost to the department, provide voice mail and new features to all employees, upgrade network equipment, and your overall monthly phone bill will be less than you currently pay. However, if the department requires more phones, or employees wish to upgrade, for example they upgrade from a single-line phone to a 7460 with 6 buttons, the department is expected to pay for the upgrade. Likewise, if faculty or staff need a soft phone in addition to an office phone, the department will need to purchase the soft phone software. This system is expected to save MSU over 1.5 million dollars over 5 years. If you've ever built a house, you know that your budget can easily be exceeded by changes and additions. Phone system expenses will be billed back to departments as a component of the monthly phone bill (see What will my monthly phone bill be? below). ITS will make every effort to accommodate users with the same functionality that they currently have (at a minimum) while lowering their monthly phone costs. The majority of employees will greatly benefit from VoIP features, increased productivity, additional safety, and lower costs. In either case, the key is to control excess costs during the implementation and deliver the project on budget, and pass the savings on to the university.

What will my monthly phone bill be?

This will ultimately depend on the final cost of the system including all phones, installation, cutover costs, and incidental costs. Currently, a phone costs $17.35 for a phone line and $5.50 for voice mail for a combined cost of $22.85. The VoIP phone system is budgeted to cost $13 to $15 for a phone line including voice mail. (voice mail will be a no-charge item) The final monthly billing will not be known until the project design, implementation, and finance charges are complete.

Will my phone number change?

Nearly all numbers will remain the same. However, the amount of numbers in the 389-xxxx blocks are nearly completely used up so some changes are needed. The numbers on dial-out modems, credit card validation machines, hallway and classroom phones will likely change and will not be direct-dial numbers from off campus. However, a pilot number will be available and you will then be prompted to dial the phone's extension. For the most part, internal dialing will remain the same (by simply dialing the person's extension) and phone numbers will remain unchanged.

Will my telephone set be changed?

Yes, with a state-of-the-art IP phone. Three types of IP phone sets have been selected to replace our current equipment. The type of phone you receive (listed below) will depend on your existing phone.

  • Cisco IP Phone 7912: This single-line phone is equipped with various easy-to-use features, including call display and on-hook dialing. This phone will be used primarily in classrooms and hallways. It has a speaker, but does not have speaker phone capabilities (it has a speaker, but no microphone).
  • Cisco IP Phone 7940: This two-line set has a large, pixel-based LCD display which identifies incoming messages and categorizes them for users on the screen. Numerous other features, such as call display and an integrated directory service, are also standard on this impressive phone.
  • Cisco IP Phone 7960: This six-line phone also features a large, pixel-based LCD display. This set is dynamic and designed to grow with system capabilities. Features will keep pace with new changes via software updates to the phone's flash memory.

Most departments will also have several analog phones (i.e., in part-time offices and labs). Users remaining on an analog phone will be upgraded to an M9009 Meridian phone. This is a single line set, with call display, a message waiting lamp for voice-mail, and other enhanced programmable features.

What features will be available on my new IP phone?

The basic features on every phone line are currently being programmed into the new system. Enhanced features such as speed dial, call display, or distinctive ringing, can be customized by the end user. One of the most important features will be the ability to alert you in emergency situations such as tornado warnings, bomb threats, lockdown conditions, or other emergencies. Campus phone directories will be available on the phone's display. Integrated messaging will enable you to receive voice mail via your MavMAIL inbox. IP phones enable your phone to become an information center. Video conferencing is available at your desktop or laptop, and the capability to use your computer as your telephone while you are off campus is also availble using VoIP technology.

Will my fax number remain the same?

Yes. All fax numbers will remain with the current number. Provisions for migrating to digital fax servers will be implemented during the second phase of this project.

Will I still be able to access my voice-mail from off-campus?

Yes, the procedure will remain the same but the access number will be different. The new number for retrieving voice mail is 389-xxxx. Note: on your Cisco phone you can just press the Mail soft key to retrieve your voice messages. If you want to access your voice mail from someone else's phone, you will need to call the voice mail access number 389-xxxx. Alternatively, you can access voice mail through Outlook.

Will long distance calling remain the same?

All those with long distance privileges are able to place a call in the same manner -- by simply dialing 9, then 1 and the number. However, if you presently use an authorization code to dial long distance, then you must press *9 and then a 4 digit authorization code, and then the number you wish to reach. Note: 4 digits must be entered for the authorization code. Therefore if your authorization code contains only 2 or 3 digits, then leading zeros must be entered. (For example, if your authorization code is 86, then you must enter 0086.)

Will this new system affect my computer?

No. Even though your computer will connect to your new phone using the same computer jack, the transmission of your phone calls will be carried on a separate virtual local area network (VLAN) that will provide additional scurity to both your computer and your phone.

Will help and training be available for this new system?

Yes. Your department coordinator will respond to all of your questions/concerns. Online tutorials are currently available and classroom sessions will be offered through ITS. Pamphlets and instruction guides will also be distributed along with the deployment of your new phone.

Will my phone work during a power failure?

Yes! Power is supplied by the network. However, if you choose to use a standard cordless phone instead of a VoIP phone, your cordless phone will be unusable when power is out.

Is VoIP secure enough given security problems and hacking on the Internet?

Security of voice communication is a major concern for ITS. As a prerequisite for VoIP, we've implemented much higher security for the network that defends against eavesdropping for not only voice, but all data communications. We've done this by implementing Cisco's recommended security standards. Cisco has recently certified security of their voice systems and has received some of the highest security rating.
