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.

I found Twilio to be excellent and very easy to use for a programmer in all aspects related to voice, SMS, and other features utilizing their API. I found the node client to be excellent and helpful. We previously used the Apex client for Salesforce before it was discontinued. Although we try not to use Twilio from Apex anymore, using that client was easier than implementing our own.

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.

  • Segment’s email identifier is case-sensitive, which is ridiculous because emails themselves are not case-sensitive. This means that if I send a capitalized email address in an identify call, it will create a duplicate user rather than matching it with the lowercase email. I think this is a technical oversight that should be corrected.
  • I’d like to see more information about the eventual transition of existing Frontline customers to Twilio Flex
  • I’d like to see some integrations between Twilio Studio and OpenAI or another open source LLM to provide automated responses, if this hasn’t been done already
  • I would like to be able to drag and move the actual lines connecting the steps in Twilio Studio, sometimes mine can get pretty messy
  • I think a Bug Report form would be beneficial for developers

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.

Unless we can get this handled quickly -- less than 1 week -- we will likely switch to another provider who, in my opinion, we'll have to spend close to $3,000 in development time to build a new integration for texting. Our clients need texting and I feel Twilio has failed us miserably.

Usability
Avaya
Avaya IP Office is a great system that is somewhat affordable for most SMB's. However, In our experience, Avaya IP Office has a tendency to shelve some of the license as you upgrade the software release on the PBX switch without giving back any comparable license to compensate. The Voicemail Pro license is quite expensive and most of the functionality that most business needs are not covered in the standard voicemail offering.

Twilio has well documented APIs and examples. There are several tutorials, videos and Q&As regarding their services. So, usability is very good. I must say that advanced knowledge of telephony, API/Programming and error-handling is essential to make good use of Twilio. It's not just plug-and-play unless you are integrated with a system that has all of the programming built for it.

Twilio executes what it is designed to do: send SMS messages at scale while providing very good deliverability. I believe that Twilio is very good at what we use for adding SMS messages to our comms strategy. We can see those messages get opened and replied to, which is exactly what we are looking to achieve.

I have not had to communicate with Twilio support in the last 3 years but my past experience with them has been very positive. They replied to my previous requests promptly and kept me well informed to resolve my inquiries. With their documentation that's available, I hardly imagine why anyone would need to contact support since it's all there in a concise and easy to understand format. It would probably take you longer to type out a support ticket than to just open their doc websites.

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. With the Avaya brand behind the system, there is also a form of working with a Trusted partner with many years in the UC space.

We evaluated many fundraising-based text-to-give programs and found the subscriptions prohibitively expensive for our small scale and uncertain first few years of development. While we may be willing to invest that kind of money after discovering how things work, we're happy with Twilio now and have no desire to start over.

  • 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.
