Asterisk Phone System Enhancement

Job ID: 37858082

Budget: $250 – $750 USD

We used Asterisk as our phone system
And we used Flutter's Sip-UA as a client
The communication platform is WebRTC
The problem we have is that when the internet suffers a few packet losses during a call, the client leaves the channel and then it is completely silent until the call is disconnected.

We simulate the same scenario with a softphone, after the internet is disconnected and reconnected, the call continues and there is no problem.
Are there any friends who can guide me?
