Release Notes for Mobile SDK 5.2.22¶

New Features¶

Android¶

• #1875: In case the license verification fails, cache files created during verification are cleaned up so subsequent verification attempts will start from a clean state.

Issues Fixed¶

• #1854: The duration field in the call statistics no longer resets after network change.
• #1879: Change in IP on the same network interface, for example when switching cellular technologies, is now handled correctly.
• #1884: Better handling of WebRTC interface pointers to prevent native crashes during transport construction/destruction.

Known Issues¶

• SDK cannot be initialized on an IPv6-only network with no IPv4 support and no NAT64
• #426 - On Android, SDK cannot use NAT64 networks. This is a limitation of the operating system. Use dual-stack SIP servers to support IPv6 only clients.
• #365 - WiFi to WiFi handoff can cause the call to disconnect if the handoff is too slow (~30 seconds), especially using TLS transport.
• #135 - DNS SRV isn't supported.
