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.
It is also vital that networks/firewalls are configured to ‘allow’ the video calls to take place on the school’s network and teacher ‘devices’ (see more on this at the bottom of this article).
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 can be done simply by asking teachers to login to their Parents Booking account and click the ‘Video Settings’ button on their Dashboard. This will allow them to test their internet browser is compatible, and that their webcam and microphone work. Teachers can also run the ‘network test’ detailed in Test One above.
The instructions (PDF file) for teachers on how to join the video calls goes into further detail on internet browser and device compatibility.
This blog post details how to set up a more cumbersome but in-depth test, where you set up fake parent accounts and have teachers and ‘fake parents’ book appointments between each other.
Information for Edinburgh Council schools:
At the time of writing schools/teachers should not use the LTAD network for their view meetings as this seems to be blocking the video meetings (although it does seem to work at some schools). Please advise teachers to use either the LTAP_P or LT_Open networks.
Information for your IT/server team:
Media / UDP Network Settings :
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, making any network adjustments required.
Ensure *.Twilio.com URLs are whitelisted.
Smoothwall users should add Twilio.com to ‘authentication exceptions’ in Smoothwall’s policies. Some Smoothwall users have also had to modify the’ default outgoing policy’ to allow ‘any internal interfaces’ to access ‘any external interfaces’.
We are also using Twilio’s Irish (ie1) “media servers”, which use the Twilio IP address ranges listed below:
220.127.116.11 – 18.104.22.168
22.214.171.124 – 126.96.36.199
188.8.131.52 – 184.108.40.206
220.127.116.11 – 18.104.22.168
