Outgoing call - rings once them goes silent

[stre1026]

I have a client with a hosted 3CX instance. When they make outgoing calls, it rings once and then goes silent until the other party picks up or their voicemail does. Flowroute does not see anything on their end. It also doesn't happen internally and I'm not noticing it on my 3CX app. I'm told it doesn't happen every time either but happens on a majority of their outgoing calls. Any ideas?

I am having similar issues reported from users. Interesting that we are also using Flowroute, but not hosted by 3cx. I have not contacted them yet as its an intermittent issue currently.
