Considered Both Products

Chose Avaya Unified Communications
We used Weave for less than two years. It didn't have any performance tracking capability, and it could not handle our call volume. Once the call volume reached a specific peak, incoming patient calls would automatically drop, which negatively impacted the organization. Thus, …
Chose Avaya Unified Communications
I Don't see any major difference between Avaya UCaaS and other similar products which includes webex, microsoft teams and google meet. All of them provide more or less similar functionalities and have all integration. However, Avaya UCaaS is more holistic when compared to …
Chose Avaya Unified Communications
SSO was not available for our former Avaya IP Office on-premises system, and after the pandemic, we needed hybrid work, so all workers could work from home and this ushered in the age of cloud for us with Avaya UCaaS: Cloud. It is our choice now only because our workforce is no …

Chose Avaya Unified Communications
Apart from Cisco Webex Calling/app no other vendor offers their own phones hardware, gateways. We need to add other vendors like yealink, Poly, Audiocodes to complete the solution. This makes things very difficult from management perspective. As you have to hire a person who …
Chose Avaya Unified Communications
Avaya Cloud Office maintains important features that others do not (such as e-faxing). Can easily transfer a call from desktop phone, to mobile app seamlessly. More cost effective than Microsoft teams once you factor in calling. More feature rich and reliable than Zoom or Webex.
Chose Avaya Unified Communications
We compare with Destiny but the integration of Avaya Cloud Office with Teams was much better.
Chose Avaya Unified Communications
Avaya Cloud Office allows each employee to have a profesionnal DN number. It is very professional

Chose Avaya Unified Communications
We have recently changed from Avaya to Microsoft Teams and being honest, MS Teams seems way better than Avaya, since it is much more stable and is completelly connected with our contacts database and emails.
Chose Avaya Unified Communications
We use CenturyLink Hosted VOIP in our executive office and the phones are way more modern looking and have more features, and was easier to implement. Hoping to maybe someday use them in our primary office.
Chose Avaya Unified Communications

Price is less compared to them and the VOIP quality with Contact center is at par with the other PBX.

Avaya is very user friendly and easy to manage in terms of operation support and user training.

Chose Avaya Unified Communications
We have used Adobe connect but Avaya ACE provides more out of box features and easier to configure.
Chose Avaya Unified Communications
The product pricing sits in the mid-high position compared to its competitor. It provides the most features when compared to the competitors. It has excellent support which can only be matched by the more pricey competitors, however, the lack of 24x7 support can be a challenge …
Five9
Chose Five9
Just tried to keep it simple. For this call center, I only need people to focus on making as many calls as possible. It is very streamlined and makes things basic for the reps without needing extensive training.
Chose Five9
We use Five9 as a tool to make and receive calls from various departments such as Customer Care, Underwriting, Claims, and others. These departments have experienced issues primarily from supervisor consoles because they sometimes lose access without making significant changes …
Chose Five9
As we have Salesforce for our agent's member support platform, Five9 has a very good integration with Salesforce compared to Talkdesk. With the iVR customization for our order placement and scripting for agents, we preferred Five9 over Talkdesk.
Also, for our enrollments, …
Chose Five9
Five9 has a much better integration with salesforce and allows contact center agents to be separate from back office staff that do not use the Five9 phone. Five9 allows us to route digital activity such as emails and texts just like we route calls. Five9 also had a …
Chose Five9
With Avaya Call Center Elite - Muti Channel is was competitor to Five9 which tried to push their on-prem omni channel approach. The reason it coudl not compete against Five9 was because it was not cloud based, was not flexible and added addional channels as an add on the CC …
Chose Five9
Five9 has a great learning curve, whether you're an admin, agent, or supervisor. Each role can be easily learned and mastered.
Cost was a major factor back when Five9 was the only stable and reliable contact center solution. But now they tend to be overpriced compared to Genesys …
Chose Five9
Five9 has way better features than RingCentral - Five9 has way better features including the Call script, software integration, and ability to manage outbound campaigns while RingCentral doesn't allow these features
Chose Five9
Five9 allows to call automatically to the leads in Hubspot, this wasn’t possible with Justcall.
Chose Five9
Initially selected Five9 but have since switched to RingCentral which has given us what we needed. Better CRM integration, simpler and in my opinion more robust reporting capabilities and the same omnichannel solution at a fraction of the cost.
Chose Five9
I currently use Gong.io at my current company, I really like the dashboard of Gong.
Chose Five9
We started evaluating Zendesk Talk when Five9 lost integration with Zendesk, as we use Zendesk as our primary CS database and issue tracker. However, Five9 offers better ROI than Zendesk Talk given we require unlimited minutes for our requirements, thus we continue with our …
Chose Five9
While we use Invoca and Leadspedia for more granular tracking and data, Five9 has always sort of been the end all be all. If it's in Five9, it's pretty concrete that the info in Five9 is the correct information. It doesn't matter which campaign a call came through, if it came …
Chose Five9
We recommend Five9, with 2 major reasons: Its flexibility on contract terms and base contacts are less restrictive.
Chose Five9
I have not used another dialer system other than Five9. Before Five9, we dialed our clients with lists and standard phone systems.
Chose Five9
We felt that Five9 was superior to Genesys PureCloud because of Five9's ability to better manage outbound dialing campaigns. Genesys PureCloud required automation rules to reset/refresh the list position which meant that it was impossible to keep up with our aggressive dialing …
Chose Five9
Five9 has some of the same features as competitors but offers other features that help users better complete their tasks. This could be tasks such as putting calls on hold, logging calls and reports, and multitasking on the system platform. Overall, Five9 feels very easy to use …
Chose Five9
We started with InContact and were very disappointed that you could not make changes without incurring costs for each program or project. Five9 allows us to adjust to any new clients needs without incurring costs.
Chose Five9
I've used RingCentral, LiveOps, and Sendbloom Contact in my sales career so far.

Five9 is more sophisticated and offers more customizable features than all the above products. Only RingCentral and Five9 have texting ability, but neither solution is perfect at threading …
Chose Five9
Used solutions from Cisco, VICI, SkySwitch in the past. Comparing cost, resources, and deployment time, Five9 wins for sure.
Chose Five9
I would use Five9 verses another application because it is user friendly. You can add users and manage them as your business grows, and have your stats easily accessible. The ability to use it remotely is a huge factor as well.
Chose Five9
Five9 blows Serenova out of the water. Serenova is an immature platform compared to Five9. Five9 provides many features that Serenova does not and is a much more stable platform, which is absolutely critical in our 24/7/365 environment.
Chose Five9
Better than the old ShoreTel Director we had prior to deploying Five9. But could be better!
Chose Five9
When we chose Five9, it was largely due to the research of features and functionality, plus hearing good things about it from other contact centers in our area.
One huge edge that Five9 has compared with other dialers...is that you don't pay per minute of talk time (unless it's …

Call centers where lots of calls come in per day are better suited for Cloud office. Small businesses or companies that don’t really make outgoing calls or receive a lot of incoming calls other than within the company would not really be suited for Avaya Cloud Office.
Read full review
very well suited for large number of enrollments, registrations by insurance companies. Also we recently implemented it for automating a order placement. Maybe not very well suited for live agent chat experience as there are limitations on texting, laggy performance in this area. I think its also hard to incorporate a payment system within the five9- salesforce automation.

Pros
  • User-friendly GUI management interface with the possibility to create different rooms, notebooks, calendars, and chats.
  • The management interface for recordings is made in the rooms with the possibility of downloading them to the location.
  • Link and file sharing with other participants.
  • Chat with all participants and individual.
Read full review
  • Inbound and outbound calls it process is so well.
  • The service is so good and they give very efficient support in customer need.
  • The calls we can do in Five9 include incoming, outgoing, voicemails and we can also send a note to a specific person. It's a very reliable mode of communication.
Read full review
Cons
  • Avaya has very strong contact center offerings and more contact with our salesperson would be helpful, so we can explore the latest offerings
  • Although it's adequate a slightly more intuitive UI would be helpful
  • More integrated reporting at the end-user level.
Read full review
  • Text. Texting is incredibly difficult on Five9. We've had issues with only some texts logging to Salesforce, issues with threading of text conversations, and issues with having Salesforce contact information appear on the text widget (knowing who you are texting, not just their phone number).
  • The interface to "pause" is challenging. There are not good reminders to our reps to remember to pause or log out of Five9. If you forget to log out, this can affect stats about who worked the longest hours that day - and it's hard to know who actually was active on the phones.
  • Inbound voicemails are too-easily hidden. It's challenging for a lot of our reps to remember to check their inbound voicemails because it is hard to access them in the Five9 widget.

Likelihood to Renew
Things change, business requirements change so when we come to renew we may explore other options, we might go all in on Teams or look at something different - we need something that allows us to increase and importantly decrease our licence count more flexably which Avaya / Ring Central don't allow.

Robust product, great reliability and support.

Usability
There are few times that we have not been able to take advantage of the tool, but those moments are related to the bandwidth of each person in [their] home. Those who have low signal cannot access meetings on the platform smoothly.
Read full review
I wish it was a 10. For the sake of a call center, it allows me to keep it simple for newer sales reps and just focus on basic KPI's. This is not an advanced CRM used for digital approaches. It is strictly a churn and burn call center CRM for me. It is a dialer.

The system's performance is great. Page loads quickly. Reports are generated quickly and sent to our email or FTP. The integration did not impact the performance of our other applications. We have not seen any drop in the performance of either applications since we performed the integration.

Support Rating
The Customer Service and Representatives are always kind and willing to go the extra mile to get anything resolved. Yet, we have not really needed them after the initial set up since the product actually works and we have not really experienced any major issues.
Read full review
Five9's Customer Support team is also based in Manila Philippines, thus turnaround email response times for our reported issues are great for our requirements. Their CS agents also facilitate mobile calls to followup on outstanding issues and operate on a 24/7 schedule. We've also had experience working with the senior tech agents to investigate recurring issues to completion.

I took the certification course for administrator and also received some tips while working with the developer during implementation. The UI was very intuitive, so I was able to figure out how things worked when I configured the users, skills, campaigns, IVR scripts. I worked with the Five9 AI team to beta test Agent Assist.

We used Weave for less than two years. It didn't have any performance tracking capability, and it could not handle our call volume. Once the call volume reached a specific peak, incoming patient calls would automatically drop, which negatively impacted the organization. Thus, our decision to move forward with Avaya was solidified.

We use Five9 as a tool to make and receive calls from various departments such as Customer Care, Underwriting, Claims, and others. These departments have experienced issues primarily from supervisor consoles because they sometimes lose access without making significant changes to the admin console. Although it's a tool that has helped us complete various tasks to contact our customers, it has also allowed us to replace Zoom Phone, as it makes it easier to assign new contact numbers to agents, while Zoom Phone only allows reusing numbers.

A good tool with an easy interface for new users.

They need a more minimalist look.

They need to improve the supervisor console because it's very basic.

New agents aren't receiving calls from previous agents because they don't reuse numbers.

The user group license is cheaper than the Zoom Phone license, which allows for a better ROI.

It was very easy to add additional licenses. Once we placed the order, it was activated the following day. Since it's web-based, it's very quick to deploy across multiple sites.

Return on Investment
  • Moving on cloud calling did save us on costs of managing on-prem infra
  • Since Avaya UCaaS has its own make phones and gateways it saves on support costs due to multiple vendors
  • It lacks many third party integrations available in MS teams, this makes making workflows difficult
Read full review
  • ROI was not as anticipated due to lacking reporting functionality - Negative
  • Allowed us to develop a geographically dispersed call center workforce in response to the pandemic - Positive
  • Provided true omnichannel capability that we lacked in the past (Voice/Voicemail/Chat). Positive
  • CRM integration (with Salesforce) was not as expected. Negative
  • Bang for the Buck just was not where it needed to be. High cost solution. Negative.
