Module error_code 

The ERROR-CODE attribute and the codes defined by STUN, TURN and ICE. The ERROR-CODE attribute.

An ErrorCodeAttribute is a numeric ErrorCode plus a reason phrase. The codes here span three specs — STUN’s own (400, 401, 420, 500), ICE’s role conflict (487), and TURN’s allocation failures (437, 441, 486, 508) — because all three share this attribute.

ERROR_REASONS maps each known code to the phrase it is normally sent with, so a responder does not have to invent one.
