    I do think Google Voice works well for organizations that do not have a support team meant to provide regular telephone support, and instead do so on an ad hoc basis. I would not recommend it for high-volume call activities, such as SDR motions.

    I feel the product is very good to set up basic standards and go beyond that in many aspects. However, due to being sometimes too simple, it limits the ability to do some other complex changes. Having the ability to do both would be ideal for some, if not all, of the products within Zscaler Internet Access. A simple setup to have it stand-up, and more advanced settings for those more experienced.

    • The voicemail inbox is a great feature and you can see when messages come in online and listen to the messages from your computer.

    • Better visibility into failed posture devices, including a timeline and the reason the posture failed (This is about the Zscaler mobile portal: Enrolled devices --> Failed posture devices).

    Google Voice has been invaluable for us in our effort to provide exceptional customer service. With Google Voice, we have been able to increase our customer interactions while reducing the wait time to reach a live person on our team. We couldn't be more pleased with the way things have worked out since implementing Google Voice.

    While Zscaler Internet Access (ZIA) delivers critical value in cloud security and RBI compliance, I rate renewal likelihood 7/10 due to evolving needs versus platform limitations. Below is my rationale:
    Key Gaps:
    1. Advanced Threat Costs:
    ZIA’s add-ons (e.g., Advanced DLP, Sandboxing) incur 35%+ cost premiums – straining budgets as transaction volumes (UPI/iMobile) grow 50% YoY.
    2. API Banking Scalability:
    ZIA’s API rate limits throttle real-time policy sync during UPI peaks (10K+ TPS), forcing workarounds for finacle integrations.
    3. RBI Future-Proofing:
    Limited native support for upcoming digital rupee (CBDC) security rules requires custom development, increasing compliance overhead.

    I think it works really well in the arena it operates in, but not so well in areas where an enterprise system would be more appropriate. It's great for quick solutions that just work, but not so much for more complex call management tasks.

    Getting started was pretty straightforward. We can tell the product is way more robust than we are using it. It started as a replacement for previous DNS-blocking content filtering, but we're exploring how this will add value with an upcoming DLP redesign and with traffic optimization at some of our remote sites with severe bandwidth limits.

    They do not offer support unless you have the Business account for Google Voice under G Suite. This is tough, because Google doesn't really have a customer support team for this service, so when it gets shut down for a few hours, we have no choice but to wait it out. But this doesn't happen that often, which is great.

    Zscaler's ZIA support is quick and knowledgable. They respond within 1-2 hours of you submitting your ticket. They are very thorough and are typically ready to jump on a live troubleshooting session. Our ZIA platform and how we use is it unique so at times tickets can be open for weeks but we alway get quality support compared to other unrelated product support in our enterprise

    The integrations of Google Voice with all our devices are flawless, Android, iOS, Windows, Linux and Mac. Also, the call performance is far superior on wifi as well as on mobile data. With Skype, we had several problems with personal accounts, performance issues, and in general, it felt awkward to use it.

    The overall user community and scope of supportability outweighed the others on our short list. Netskope was a close second, but the risk, though small, was greater than that of bringing Zscaler aboard. We were looking for a mature, well-supported, highly functional, and fine-grained solution that met all our user and information security requirements.

    Google Voice should be also be use to those who have difficulty in speaking English. So the contract term will need to be a little strict as Google Voice is used in navigations as the part of GPRS navigation is personal. The private data need to be in control much more securely and safely.

    Return on Investment

    • Cost for Google Voice is stellar, starting at $10/mo per user.
    • While it doesn't offer a new Audio/Video conferencing solution it does integrate with GSuite so it makes use of Google Calendar and Hangouts/ Google Meet.
    • Gets the employee's to use their company phone numbers more as texting is easy and deployment is simple.
    • The cell phone app is reliable and easy to deploy.

    • I would say it has a very good ROI, as whenever someone can't access something, they submit a ticket to our network engineer, and within minutes, the site is safely added to ZIA with best-practice configurations. After seeing a little of the UI from the Zenith event, it seems very user-friendly to control these policies.
