Disclosure I work at Splunk and VictorOps is a Splunk product. But I would suggest in addition to trying the others adding VO to your list. It's important to note that some of the tools are designed as Incident Response tools, others started as mass notification tools. For on-call stick to those designed for incident response.

I would say to use Squadcast, the configuration is easy, provides a lot of features such as war room, RCA tracking postmortem, RBAC and they are quick to add features on request as well, recently I asked for custom on call reminders and I am sure they will add it really soon.

I consider Skype dead. Even Microsoft strongly neglected it. Webex is more corporate-oriented. So for your use case, I recommend Zoom. It is easy to set up, and the quality is very good. Zoom became such a household name that the average person heard about it. Moreover, any person probably has friends who may have used it. So it will be easier for people to get some community help.

We've been using Zoom for about a half a year and it's stability is unbeatable. We have all-hands on Fridays with 100+ participants. The free tier can easily handle the requirements, the only limitation is that max meeting length is 40 minutes. After that you can immediately restart the meeting, but the pro option is also very affordable. It also features screen sharing and whiteboard sharing out of the box. I also appreciate that it's not mandatory to register an account to attend a meeting.

Hi, Lisa,

I haven't used Skype in a long time. I have I lot of experience with Zoom and Webex. Both for me are very good tools, especially if you have money to pay for (to unlock more features, like more people in a video conference - Zoom).

Nowadays, I've used more Webex with my undergraduate students, I'm using the free account. Cloud recording is a features very useful, especially while using the free account (thanks Cisco!). Webex has control features very useful (e.g., mute, raise hand etc).

Kind regards,

From my experiences I feel like Zoom is a pretty intuitive program to teach kids, however Skype might be more common amongst them already.

I am a big fan of Microsoft Teams.

They all do the same pretty much but Teams I find the bells and whistles are easier to find, like custom backgrounds... creating groups for topic discussions that remain there until you want to change/edit or delete. Easy to share files.
