Release Notes 5.2.19
Date: 2019-10-07 Issues Fixed General - Fixed calculation of jitter statistics in the getStatistics() API and added jitterBufferMs and preferredJitterBufferMs fields to track local jitter buffer size. - Fixed crash in case of malformed license key - return a key format error instead. Android - Fixed crash in some network change scenarios - Fixed audio freeze during network change (regression from a previous version) - Fixed mUTF-8 formatting for log messages pushed through JNI - Fixed initialization when no network connectivity is present when SDK needs to load runtime configuration and check license. Instead of hanging with no callback, SDK will now send onLicense() event with licensing state set to LICENSING_KEY_NETWORK_ERROR so the application knows to retry once network is online again. - Support non-alphanumeric characters as contact address in dial*() APIs. When specifying non-alphanumeric characters, the SDK will URI encode these according to RFC 3986. The receiving application can decode these and perform whatever application-specific logic it requires, or completely ignore the encoding as the resulting text is ASCII-safe. Known Issues Mobile SDK - SDK cannot be initialized on an IPv6-only network with no IPv4 support and no NAT64 - 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. - WiFi to WiFi handoff can cause the call to disconnect if the handoff is too slow (~30 seconds), especially using TLS transport. - DNS SRV isn't supported.
