|
* ICE Resolver for Jingle transport method that results in sending data between two entities using the Interactive Connectivity Establishment (ICE) methodology. (XEP-0176)
|
||
|
|
* The goal of this resolver is to make possible to establish and manage out-of-band connections between two XMPP entities, even if they are behind Network Address Translators (NATs) or firewalls.
|
||
|
|
* To use this resolver you must have a STUN Server and be in a non STUN blocked network.
