The others have a ton of built-in features that are very nice to have with a traditional PBX or CC platform. For some companies, these aren't necessary. Twilio is great because, if you have a very specific use case that doesn't involve most of those other features, then …

So I haven't had one where it's not appropriate at all unless somebody was going pure cloud. Obviously, this is not a cloud product, but from an on-premise solution like the IP office is, we've sold it to companies that have five users and we've sold it to customers that have thousands of users. So it's very expandable, adjustable to be it's hybrid, so it's IP and digital mix capabilities. So that's a strong suit.

Twilio excels in customer service applications, enabling automated SMS updates or voice calls for order confirmations and support. It's ideal for implementing two-factor authentication, enhancing security for online services. However, it's less suitable for businesses needing in-depth, custom telephony infrastructure, as it primarily offers standard, API-driven solutions, or for regions with limited internet connectivity, where cloud-based services may be unreliable.

Pros
Avaya
  • Centralization is key. If you want to have all of your facilities on one phone system, to help mitigate telecom costs this is the system for you. You purchase the necessary licensing (one time purchase) and the licenses stay with you as long as you stay on that platform!
  • Flexibility is fantastic. Whether you want to use the IP Office as a key system, or replace your existing partner system, or run as a PBX. This system will do it all, I was very impressed with the compatibility of the IP Office with legacy equipment. Have a Partner system? Not a problem. Have a Definity system? Not a problem!
  • Broad based technology. You can utilize CO trunks (POTS lines), ISDN/PRI, T1, SIP, etc.... What ever your carrier hands off to you the IP Office can integrate with. No need to work with a third party vendor to get your interface up and running. AVAYA is a one stop shop, and if you have an existing warranty, just upgrade your IPOSS information on the system and your new hardware is covered.

  • Easy to see my team in one place, when they log in and out and what call status they are in.
  • Twilio is a simple, user friendly way to log in and out of work activities.
  • Excellent services and support.
  • The omnichannel feature which allows agents to get request from all channels.

Cons
Avaya
  • Rush for updates. At times an updated will fix one problem, and inadvertently create another. However with due diligence from your business partner (Tektivity) patches are tested before being rolled out in production environments.
  • Part itemization. If you purchase a new system, the power cord does not come with the unit, that is a separate part. Very minor in the grand scheme of things but as a reseller and a customer still somewhat annoying.
  • Large convoluted organization. As a user trying to navigate the AVAYA website, and track down information can be daunting. Even calling support can be challenging, you never know if your call will be routed to India, Brazil, or Denver. That is why the relationship with Tektivity is so important. You can leverage your business partner to get the answers you need so you can spend your time tackling issues that need your attention.

  • In my opinion, online support is extremely subpar for clients.
  • In my experience, no way to talk with anyone without a $1,500 investment monthly in their service.
  • In my experience, be prepared to wait at least 2-4 days to receive even one response from their support.

Oddly enough I have been impressed with the IP Office platform so much that I have integrated one into my home. My wife was not happy with it initially but once she started using it she was very happy with the results. It helped that I programmed it to work just like a home phone but with features and options that I can utilize remotely. I would be more than happy to put an AVAYA IP Office against any other phone system on the market, and let you be the judge.

We have standardized our processes surrounding Twilio. The entire process just works! There is no significant gap that we need to fill. Instead of thinking about Twilio's replacement, we'd rather focus on our customers with Twilio. It meets all our uses-cases currently. We haven't even explored the entire suite of applications to determine what other use cases we may potentially use.

Overall the product API is extremely well documented so it is very easy to build a product with their technology. The website is a little bit cumbersome to use as they have greatly expanded the number of products that they have over the years, but the dashboard UI has not been improved much since.

The problem tends to be us, the user, rather than Twilio. We don't reach out to support fast enough (spend time struggling), but when we have, they've solved our issue immediately. We are rural, so there are signal issues to accommodate, however, we find that a few staff on a few cellular networks can triangulate where we all have signal to put up a sign.

I've never had to contact Authy's support. Of course, that's because Authy is so simple and easy to use that there hasn't been any need to. Authy correctly implements the time-based one-time password (TOTP) protocol, and becomes it conforms to the standard, it easily replaces Google Authenticator for your needs.

Much better feature set with Avaya IP Office, and I really feel you're getting feature-rich telephony for a well priced switch. The system is very adaptable and a much better fit than legacy key systems and cloud-based UCaaS solutions competing in the same market.

Twilio was referred to me by a business colleague, and I can't be more thankful! Twilio has helped my Facebook page by leaps and bounds, and I haven't even considered trying another chat option for my page. It is easy to set up, and customer service is quick to answer any and all questions you may have. I highly recommend it!

Return on Investment
Avaya
  • When selling to a prospective customer, I always do a 10 yr ROI to show the benefits of Avaya IP Office or ACO and which scenario would fit best.
  • CAPEX vs OPEX
  • Number of phones needed as well as other features need to be considered to determine if Avaya IP Office fits best.

  • Adding in phone numbers onto our onboarding sequence has increased our user activity by about 30%. We believe due to the users being more invested in the application now.
  • On top of that, our first SMS has increased our week 1 retention by about 15%. Pushing users to go on the app more than 2-3 times has been a struggle and SMS seems to be a solid driver in retention.
