If Asterisk is challenged on an outbound INVITE and the nonce is changed in each response, Asterisk will continually send INVITEs in a loop.

Outbound authentication must be configured on the endpoint for this to occur."}, {"lang": "es", "value": "Se detect\u00f3 un problema en Asterisk Open Source versiones 13.x anteriores a 13.37.1, versiones 16.x anteriores a 16.14.1, versiones 17.x anteriores a 17.8.1 y versiones 18.x anteriores a 18.0.1 y Certified Asterisk versiones anteriores a 16.8-cert5. Si Asterisk es desafiado en un INVITE saliente y el nonce es cambiado en cada respuesta, Asterisk enviar\u00e1 los INVITE continuamente en un bucle. Esto causa que Asterisk consuma m\u00e1s y m\u00e1s memoria ya que la transacci\u00f3n nunca terminar\u00e1 (incluso si la llamada se cuelga), lo que a la larga conllevar\u00e1 a un reinicio o cierre de Asterisk.
