Skype for Business Vs Avaya

Discover the difference between Skype for Business and Avaya with our comprehensive comparison guide.

Avaya is a service offering various communications solutions across conferencing, infrastructure, cloud technologies, customer experience management and networking. Their unified communications (UC) platform is often seen as a competitor to Skype for Business, Microsoft’s alternative UC. 

This is a guide to compare Skype for Business against Avaya to help you decide which is more suited towards your business needs. Alongside this, we then introduce VIA UC, VIA’s advanced Skype for Business solution, as it offers even more features that Microsoft's standard package.


Avaya’s UC platform has a capacity limit of 64 people per conference call and smaller limits for other communications.

Skype for Business and VIA offer 250 participants per any communications regardless of web application or mobile. VIA UC, however can grant more participants should a business require it, just get in touch. 


Avaya’s capacity of 64 is not considered enough for most business conference calls in the modern day. VIA and Skype for Business lead the way with the former offering more seats if a business requested it.

Call Hardware

Skype for Business and VIA allow for connection to existing telephony communications and will integrate into your current deskphones and headsets if needed. In addition to this, bluetooth headsets can easily be connected to both platforms. Avaya, however, requires the user to use their approved hardware, bought from them or their partners.


For up to date, hands-free technology Skype for Business and VIA offer a better platform due to Avaya’s lack of connectivity and restrictive hardware policies. 

Future Support

Avaya is a product that must be purchased through third-party resellers, meaning the support available is dependent upon the company purchased from. This could mean delays in support as support queries are transferred from the third-party to Avaya.

Skype for Business direct from Microsoft only has community forums to the support the whole product. 

VIA has its own 24/7 UK support on the phone and online whilst also offering trained installation assistance in-person with a qualified engineer.


For 24/7 access support through a business representative, VIA will definitely offer you more for your money.

Avaya’s support is dependent upon the third-party reseller and is only offered online; there is no 24/7 call support.

On-Premise Equipment + Cloud Technology

Avaya is normally installed as a hybrid technology, which requires hardware on-premises, similar to some installations of Skype for Business. 

Some installations will not require hardware, but this would be dependent upon business size and would need to be certified with Avaya and Skype for Business. 

VIA’s Skype for Business platform, VIA UC, hosts everything on the cloud, meaning remote updates can be performed and no equipment is hosted on-site. 


For an entirely cloud serviced product, VIA UC can host and maintain the equipment away from your business.

Avaya and Skype for Business may require equipment to be set up on your premises, which does not have the benefit of remote updates. 


As mentioned, hardware is often required for these installations, which can come with issues surrounding product refurbishments and recalls. This is an extra burden on the business, increasing costs and taking time away from your IT manager. 

Microsoft’s Skype for Business and Avaya’s UC solution often require on-premise maintenance, a worry that is removed with entirely cloud-based systems like that from VIA UC.


 VIA UC allows IT managers to maintain other projects as they don’t have to spend time, money and resources on keeping equipment updated. 

Avaya and Skype for Business offer on-premise options for your communications, however this can become a burden for your organisation. 

Microsoft 365 Integration

Skype for Business and VIA have the benefit of Microsoft being the most used business software in the world. Most businesses use some combination of Word, Outlook, OneNote, Excel and Powerpoint. 

Skype for Business and VIA offer full integration with all applications of Microsoft 365, whereas Avaya only offers Microsoft Exchange support. 


For full Microsoft integration, utilising Skype for Business and VIA’s UC solutions will be advantageous over Avaya’s very limited accessibility.

Feature: File Transfers

Microsoft’s Skype for Business and VIA UC both offer file transferring during calls, so sharing spreadsheets and documents is no problem during a conference call. 

Avaya, however, does not have this specific feature, and requires other services like Skype for Business to perform this task. 


If file sharing during communications is a feature you require from your UC platform, VIA UC and Skype for Business should be your preferred choice over Avaya.

Feature: Screen Sharing

Screen sharing can be useful during conference calls to show off projects or help clients visualise ideas better. 

Skype for Business and VIA both offer this service, but Avaya does not, relying on other services to perform this task.


For screen sharing services, VIA’s Skype for Business solution is the clear winner as Avaya fails to provide this.
