How to Run a Video Call Test

By October 7, 2020October 23rd, 2020News and Info

We recommend that schools run tests of video call module before using it for real parents’ evenings, to ensure it will work as well as can be on the day.

The two tests we suggest are below:

Test One: Run a Network test using the Twilio Network Tester:

Please also note the information at the bottom of this post about information for your IT team.

Test Two: Test with Teachers

Schools should check that the devices teachers plan to use are compatible with the video call technology. This test will also guide on the school’s network’s resilience to the volume of anticipated video calls, while giving teachers an experience of a a video meeting before ‘the real thing’.

Use the instructions below to set up a test without having to involve real parents, and by having some teachers at as fake parents while others take the role of the teacher:

  1. Login as an admin
  2. Go to the Parents page and create (or upload, see below) some fake parents, and at the same time create fake students. You do not need to give the fake parents an e-mail or telephone number.
    Write down/remember the parent and student names and student DOBs, because the “parents” will use these as their logins later. When creating the students, add them to a new “Test” registration group, this will make the next few steps easier.
    Alternatively download and upload this spreadsheet of fake parents (Scottish/SEEMIS schools should use this version).
  3. Go to the Teachers page and add the students from the Test reg group to the teachers who are going to be part of the test (OR make a new, fake teacher and add the students to them).
  4. Once the student are added to the teachers, paste in an e-mail address for the teachers being involved in the trial on the Teachers page (if the teachers have not already been setup with their logins).
    If this is the first time an e-mail address has been added to the teachers’ accounts, the teachers will be sent an e-mail which helps them create a login (BUT make sure these users log out as a parent/admin/teacher before they try to reset their password or they will not be able to set up a password from the link in the e-mail, and instead will see an ‘Access Denied’ page).
    You can skip this step if the teachers have already had their logins set up (e.g. Password Sent or Setup Complete shown in right hand column of the table)
  5. Create a parents’ evening for the ‘Test’ registration group, at the dates and times you want to have a test on.
  6. Have the fake parents book some appointments, either via the admin area > Manage Booking or via the school’s parent login page, before the video meetings are scheduled to take place.
  7. Then, lastly, have everyone login 5-15mins before their appointments and join the video calls, to make sure the video calls work.

Information for your IT/server team:

Media / UDP Network Settings :

From what we know through our experience so far, schools need to allow Port 443 / HTTPS traffic and IT/network teams should be aware these video calls will happen over an encrypted peer-to-peer (P2P) connection.

It may also be helpful to ensure any *.Twilio.com URLs are whitelisted.

Furthermore, adding Twilio.com to ‘authentication exceptions’ in Smoothwall’s policies has been known to benefit schools.

We are also using Twilio’s Irish (ie1) “media servers”, which use the Twilio IP address ranges listed below:
52.215.253.0 – 52.215.253.63
54.171.127.192 – 54.171.127.255
52.215.127.0 – 52.215.127.255
3.249.63.128 – 3.249.63.255
