Known Issues¶

Mobile SDK¶

• 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 call to disconnect if the handoff is too slow (~30 seconds), especially using TLS transport.
• #135 - DNS SRV isn't supported.

Reference Application¶

• #368, #370, #509 - Some issues with handling hold/unhold state after a 2nd or 3rd concurrent call is hung up.
• #482 - App does not implement ringing tone for the caller.
• #443, #464 - When switching from registration to Registration-Free mode, application does not manage the registration state correctly. Restart application after changing registration mode to workaround the problem.
