We are receiving many questions about STUN use.
STUN means Session Traversal Utilities for NAT (Network Address Translator).
When using STUN is a good idea: If you do not receive video and audio because remote side can not send media. The reason could be that SIP sends local IP address. So you can try to enable STUN and input one of the following settings:
- stun.sipgate.net
- stun.voxgratia.org
- stun.ipns.com
