Hi,

We are seeing issues with our MiCollab system wherein users seem to be presented with an error on both the Mobile App and the Desktop App in the middle of a call, “Sorry, softphone disconnected because the incoming audio stream was interrupted”.

We are using Mitel 3330 with MiVoice Business.

There is no specific timeframe or length of call before they are presented with this.
We have turned off SIP ALG on the firewall.

Has anyone seen this before/have any recommendations on what we can check?

Thanks!
