    Salesforce
    Slack is ideal for Scrum and agile teams that need continuous communication during sprint planning, daily stand-ups, backlog refinement, testing, and retrospectives. Slack is well-suited for maintaining team knowledge through searchable conversations and dedicated channels, where experienced team members help onboard new QA analysts.

    Telnyx is well suited for general phone number provisioning as they have a large pool to choose from. There is certainly room to grow with fax troubleshooting.

    Pros
    Salesforce
    • Customer issues: Threads feature allows us to group a particular issue in a single thread and discuss within that thread. I can use the thread link to embed in JIRA ticket for tracking progress in JIRA (which is our details engineering tracking system).
    • Ability to add folder to Slack channel helps keep important information, documents easily accessible. e.g., we use this to keep a "ramp up" folder that can be used by any new joiner.
    • Global search is effective when I forget which group a particular message was in.

    • Price Matters for the flourishing organization like us. Telnyx [is] affordable to us.
    • Telnyx is very generous in terms of providing regular updates through webinar , free credits, real time support . One most important is that they are not in hurry of closing the account because of minus balance.
    • Telnyx Portal is pretty easy to navigate and manage the customized settings.
    • Among other giant SIP providers I found Telnyx with very modern and humble customer approach.

    Cons
    Salesforce
    • Would love a better integration with GitHub. For example, notifications when your PR is updated, when review is requested, @-mention in comments, etc.
    • Improved "Later" tab, for example the ability to create to-do lists or making the "Later" tab into a more powerful to-do list (annotate items with notes)
    • More powerful integrations, e.g. Google Calendar could render a calendar view within Slack, rather than sending the daily schedule

    • Number testing: Currently I need to call our fax numbers manually to confirm fax tones. It would be useful to test numbers in bulk from the portal.
    • Troubleshooting: Currently, samples are needed for each fax transmission when there are issues. And those samples need to be within 24-48 hours. It would be useful if Telnyx could do a health check out proactively to gather information on high failure counts prior to customer reports.
    • Transparency with system issues: We've run into scenarios where we wanted information on system-wide fax failures, but when the issues were resolved we didn't get root cause analysis.

    To be more transparent, I give 10 because Slack serves our collaboration needs. It provide us a good platform for team communication relaying important update within the company, it has even mobile app where you can install in your phone to monitor any updates within that team that needs your immediate attention and intervention.

    Usability
    Salesforce
    Slack has good usability. Devs that are not familiar with the platform are able to jump into conversations and start sharing code and links within just minutes. Non developers are also able to understand the layout such as the Project Managers that are keeping the projects on track. We have not seen any tickets where employees are having trouble understanding Slack.

    They utilize a private IP network back end that makes SIP configuration for inter-carrier operation difficult because they assume that projecting their private network outside is ok.

    Reliability and Availability
    Salesforce
    Yes, the app works 24/7. I don't even recall having any period that we could not use since the implementation. Even the maintenance periods are barely noticeable and our work is not impacted by it when it happens.

    Performance
    Salesforce
    Slack is a soft app, we don't have many issues with it. I recall one or two people complaining about something during our usage period, but I didn't have a bad experience. When the app is slow, usually the problem is with my computer or my internet. The app works just fine.

    Salesforce
    Whenever I've had to troubleshoot an issue with Slack (which, to be honest, has not happened very often), their online documentation has been easy to locate, easy to understand, and effective in resolving my issue. Slack's ever-growing popularity also means that there's a large community of practice out there that can be depended upon.

    They are providing services using a Freeswitch system behind a NAT router and they expect carriers to deal with their NAT network. Their support team does not seem to understand that problems caused by exposing a NAT switch to the Internet at large.

    I like Slack better than ClickUp, because I would spend 30-60 minutes a day updating my ClickUp tasks. The way ClickUp was used was very micromanaging. I billed by the hour, so I was willing to put in the time to alert the boss what tasks I was working on.
    One of my jobs used Hive - I mostly just ran it in the background in case anyone messaged me. I did not use it often.

    Easy of use and better prices. Outstanding customer service. Variety of services in telecommunication needs. Easy use of interface even for not experienced users. Migration of SIP numbers is easier. Reporting is very easy to use and customizable for our specific needs, so we can keep track of costs in an easy way

    • Due to easy SIP truncation the cost of customer approach has become very convenient internationally. We got a so much scaling to play on large customer base. And large base makes sense of large positive ROI.
