How to implement VoIP correctly

Today’s companies must adapt to new trends in technology and communication is essential for the growth and strengthening of relationships between employees and partners and VoIP is one of the (relatively) new trends that will help us implement an effective, powerful and dynamic system to integrate hardware and software focused on generating voice over IP protocol and thus have comprehensive communications.

All this sounds interesting but the question that arises is, are we ready for implementation? Neotel will give you a series of practical tips to consider to mount a robust and secure VoIP system in your organization.




Create a project plan: the most basic thing is to create a project plan that allows us to correctly configure a VoIP phone system, this schedule should integrate adequate budgets and responsibilities of each user, this schedule should represent the limits of VoIP reach, generate a schedule with dates to establish the completion of tasks or phases of implementation and additional to it know the risks that may arise in the implementation such as hardware or software failures, network levels, and so on.

Determine the VoIP need: based on the fact that VoIP technology makes use of multiple functions (advanced and basic), we must determine precisely which of these functions will be useful for the organization such as IVR, visual voice mail, conference calls, virtual numbers and number portability.

Quality of Service (QoS): the QoS function has been created in order to control the quality of calls, from this point of view, QoS will make voice traffic have priority in the network where it is implemented.

Create network tests for VoIP implementation: the network is essential for VoIP to work properly and for this we must take into account aspects such as bandwidth to use, check routers, switches, modems a. performance level and update, etc..

Evaluate providers: when selecting the VoIP provider is key to take into account aspects such as years of experience, support, user qualification and prices.

Accessing an SLA before implementing VoIP: an SLA (Service Level Agreement) is an agreement that explains in detail the responsibilities of the provider, this covers aspects such as availability, quality of service and reliability.

Security: this is a key aspect because when VoIP is used there are risks as unauthorized users to make calls, listen to conversations or make use of VoIP for long distance calls, so the VoIP provider must have appropriate security measures for this.

Establish phone number portability: it is ideal for the VoIP provider to be able to transfer existing numbers in order to have adequate availability.

You have learned a few things to keep in mind before implementing a VoIP system in your organization in the proper and correct way to get the maximum benefit.

Differences between VoIP and SIP

We have talked about the advantages of implementing and using VoIP technology in our organizations for various reasons ranging from economic budgets to availability of communication anywhere and it is key that we have defined some concepts that are used with some frequency in the world of communications because if we have at least a basic concept we can determine what type of hardware elements will be most suitable for VoIP to move like fish in the water or, in this case, as a bit in the network.

From the moment we are in search of the VoIP provider we hear some terms like SIP and, logically, VoIP, but do you know what the difference between VoIP and SIP? If not, stay with us and we will explain it to you, but before we remind you that you can acquire the Yealink terminals or the Grandstream Gateway so that your company is completely at the forefront of VoIP technology.

Differences between SIP and VoIP

Let’s start with the basics:


  • VoIP: is the acronym for Voice over Internet Protocol and basically consists of a technology thanks to which voice signals travel over the Internet optimizing their quality, reducing costs and reaching any geographical location and for this we have hundreds of elements both hardware and software.
  • SIP: is the acronym for Session Initiation Protocol and refers to a protocol that is used to implement VoIP technology. SIP protocol can be used to configure or terminate multimedia sessions within which we find both voice and video, although it is closely related to VoIP is not such technology itself.

SIP: is the acronym for Session Initiation Protocol and refers to a protocol that is used to implement VoIP technology. SIP protocol can be used to configure or terminate multimedia sessions within which we find both voice and video, although it is closely related to VoIP is not such technology itself.
