Duvida sobre MK + VOIP Prioridade

Eu pesquisei bastante no forum sobre isso achei essas regras, coloquei e vi que esta marcando blz, mas minhas duvidas, na priority não deveria ser 1 ao invés de 8?
Outra dúvida meu servidor voip tem a porta 5060 que é a de conecção mas as de comunicação vão da 10000 a 20000, eu não deveria marcar essas portas também e colocar a priority em 1 pra eles tb??
