Hi everyone,
We've been successfully running a couple of apps (iOS and Android) for the last 2-3 years using WCS.
We utilize WCS as a wss-SIP gateway connected to Asterisk. Asterisk forwards outgoing calls to our providers via SIP.
However, over the past month, we've started receiving some complaints from our customers. They mention connecting to calls but experiencing no audio on both incoming and outgoing sides. This results in a timeout due to "No RTP activity," leading to the call being disconnected.
After reviewing information on the Forum, I've tried to clarify a few points regarding our issue:

After reviewing information on the Forum, I've tried to clarify a few points regarding our issue:
- The system works well for Android, and generally for iOS, but all complaints are specifically from iOS users.
- We replicated the issue with an iOS 15 Pro terminal, version 17.1.1. The problem occurs both with our office Wi-Fi network and with 4G, leading us to rule out network issues, especially since my iPhone 11 with version 17.1.2 works perfectly.
- The log from the failed instance shows this. I also have a pcap file indicating more than 2 MB of UDP messages between the iOS device and the server, suggesting that the handsets are transmitting media (though I can't confirm this as it's wss and encrypted).
