Bruno, é sim uma tentativa de invasão!
 
usar o firewall para ele... mas nao vai adiantar, pq vc bloqueia um, e
aparece outro... então ao contrario de bloquear um ip, libere apenas
para os ip´s conhecidos.
 
Seque os dados do dono desse ip, que vc pode mandar uma reclamação por
email, para que eles identifiquem a invasao que houve com eles.
Certamente eles foram invadidos ou é de algum usuario deles mal
intencionado.

Notem que em 1 segundo o "invasor" tentou várias vezes se registrar no
sip 1013 (através do método BruteForce) pelo meu link do speedy. O IP do
"invasor" é 174.129.173.249.
 
Isso seria uma tentativa de invasão? 
 
Se sim, como ele conseguiu acesso aos meus ramais SIP?
O que preciso fazer para tirar esse cara da rede?
 
Em uma pesquisa rápida descobri que esse IP é de Washington.
http://www.botsvsbrowsers.com/ip/174.129.173.249/index.html
 
Estou alarmado a toa ou é realmente uma tentativa de invasão?
 
Obrigado lista.
