The following guide will allow you to adequately prepare your migration to the IP telecommunication service of the OMNITOTAL family.
Requirements for internet connectivity
In terms of speed, it is important to allocate 100 Kbps for each simultaneous communication (audio) on the company network and towards the Internet. If you plan on 10 simultaneous calls, the Internet connection must have a capacity of at least 1 megabit per second (mbps), both upstream and downstream.
To obtain optimal quality, you must also ensure that the Internet connection offers relatively consistent latency and that it does not exceed 100 milliseconds (ms).
Voice and multimedia priority
The Quality of Service (QoS) configured in the network hardware (e.g. router and/or switch) is critical if the Internet connection of the corporate network is shared with the computer and data network.
QoS allows prioritizing voice over a computer network to avoid problems of interruptions or jerky communications.
We recommend enabling QoS rules unless your company has an independent network for voice.
Regardless of your situation, it is important to check your organization's QoS rules to ensure optimal communications.
Refer to our QoS Configuration Guide for more information on this matter.
Reliability and high availability
To ensure a high level of availability and to improve resilience, we recommend installing two Internet connections. Although not critical to the operation, this will provide redundancy between the two links that will ensure communications.
In the event that two Internet connections are available, we recommend separate operator networks using different technologies (e.g. cable and fibre) to ensure maximum resilience and to avoid points of failure.
If the installation site has two internet connections (or if there are plans to do so), it is recommended to install equipment that allows automatic balancing to the secondary link in the event of a failure or congestion. The equipment can be a router or a load balancer.
Working from a distance
In a teleworking context, it is important to ensure that the remote Internet connection (for example, at home) offers a minimum level of quality, i.e., a high-speed link capable of handling speeds greater than 100 kbps per upstream and downstream call.
We also recommend configuring voice prioritization through QoS rules on the remote worker's equipment, where possible.
Although this is not always possible, we do not recommend the use of a WiFi network as it cannot guarantee an optimal quality of service.
Use of WiFi, 3G, LTE or Satellite
WiFi, 3G, LTE and Satellite networks are becoming more and more popular, especially when a company wants to offer mobility to its employees or to cover locations that are difficult to reach with other technologies. In all these situations, it is important to confirm some elements and to consider the following points:
The communication services will properly operate on a WiFi network, however it will be difficult to ensure optimal quality. It is possible through advanced configurations and high quality hardware to achieve an optimal level of reliability and quality but a standard WiFi network (e.g. residential) does not allow these configurations.
3G and LTE
It is important to remember that when a device connects to the Internet via a 3G or LTE network, the data plan is used to make calls and carry out communications. Your device's data plan cannot guarantee quality of service, however it is often very convenient because it is highly mobile and available in locations with no other ways to connect to the Internet.
The communication service will work by satellite but without any guarantee of quality of service. Satellite networks allow connections to locations that are very difficult to access, but this technology often brings highly variable latency, as well as other factors that reduce the quality of communications. It is often the last option to be considered.
A wired network is an essential condition for the efficient operation of the communication service, especially for audio communications.
It is important to identify the locations where the telephones will be installed and to keep in mind that these locations will require the installation of CAT6 ethernet cables. These locations may include, for example, the courtesy phone, conference rooms, cafeteria and offices. The cabling must be installed BEFORE you migrate your telephone service.
Two cables per location
In the case of a 2-cable installation per location, it is possible to use one cable for the computer and the second cable for the telephone set. Each cable must connect to equipment such as a switch or router that will be connected to the Internet. This topology makes network configuration easier and increases reliability, but is sometimes more expensive.
One cable per location
Savings can be made in an installation that uses the same cable for the computer and the telephone. The telephone is therefore used for providing network access to the computer using a serial connection. Of course, it is important to keep in mind the distance between the telephone and the computer, as the computer will be connected to a port on the telephone using a network cable.
The disadvantage of this method is that if the phone device has to be restarted or moved without being connected to a power source, the computer will be disconnected from the network and the Internet during the restart process.
Switch with power (PoE)
It is strongly recommended to use switches that support PoE (Power over Ethernet) to provide power directly over the network cable. This eliminates the need for a dedicated electrical power adapter to power the telephone set.
This may require the installation of a PoE switch, which may be more expensive than a switch that does not offer this capability, however this method will avoid the need to purchase power supplies for the telephone equipment and will reduce the use of electrical outlets.
Electrical safety and emergency power supply
With the installation of PoE switches (centralized power supply), it is possible to add an extra level of protection and security by installing a UPS (Uninterruptible Power Supply) to reduce the risk of failure in the event of a power outage. The UPS module will provide power to the PoE switch and ensure service continuity during the power outage.
Power supply unit for telephone sets
If device-based power supplies are used to provide electricity, it is important to consider the number of electrical outlets required as well as the power bars.
FAX, alarm systems and other analogue devices
Requirements for FAX
If you wish to install a fax line and you would like to keep your fax machine, you must make sure that you have an easily accessible network connection as you will need to purchase an Analog Telephone Adapter (ATA) to connect the fax machine to the company's local network. Remember that it is often better to opt for a virtual fax service that allows you to eliminate fax machines from the system.
Requirements for an alarm system
If the installation site has an alarm system connected by a telephone line, it will be important to make sure that a network connection is accessible because you will have to acquire an ATA to be connected to the surveillance center. ATAs offer an Alarm mode allowing for compatibility with this service. Keep in mind that an increasing number of alarm system services go directly through the Internet, in which case you will not have to make any changes.
Other analogue devices
In the preparatory phase, it is also important to identify any other analogue telephone sets used by the company. With this list, it is easier to determine the best approach for these devices. For example, consider:
- Stamp machine
- Interac machine or Point of Sale (PoS)
- Door opening system
- Loudspeaker or paging system
Legalities, transfer of responsibility and documentation
Existing customer contract
In preparation for a transfer and upon acceptance of the service proposal, we recommend customers to submit their recent telecom bills (less than 63 days old) for review. It is particularly important to have a list of telephone numbers and toll-free numbers for the portability procedure.
Refer to the portability guide for the procedure to follow to ensure the success of this process.
