Hi there,
We have a contact center solution built off a sip trunk via direct route SBC to teams environment. When the system delivers a call to this particular teams client via direct route, the teams client fails to create a notification toast pop with the following type script error:
2019-08-27T20:14:43.304Z Err Unhandled exception. TypeError: Cannot read property 'length' of undefined, cause: , stack: e.djb2_hash@https://statics.teams.microsoft.com/hashedjs/3.2-app.min-4528048e.js:4:350330 > o.createNotificationData@https://statics.teams.microsoft.com/hashedjs/3.1-app.min-3ff72090.js:1160:16072 > o.createVideoNotificationData@https://statics.teams.microsoft.com/hashedjs/3.1-app.min-3ff72090.js:1160:8755 > o.createVideoCallNotification@https://statics.teams.microsoft.com/hashedjs/3.1-app.min-3ff72090.js:1160:8335 >...

================================================
The packet sent to SBC from CC system looks like this:

After time out, the system pulls the call back then this call is recorded as a missed call on teams client.
The weird thing is that this exact scenario works for every other user conffigured on the tenant.
Any help is appreciated!
