il 3cx mi da problemi con le chiamate da fuori attraverso ippubblico non si sente la voce. Sapete come risolverli?
Nella mia rete lan ho un router della linksys e un firewall della zyxell (zywall)

Grazie

Il firewall deve tassativamente supportare lo static port mapping ed il NAT traversal. Nel tuo caso il firewall sta invece evidentemente traslando le porte ossia esattamente il contrario. In queste condizioni il SIP non funziona.
Non sono molti i firewall che supportano lo SPM ed è per questa ragione che la scelta è fondamentale soprattutto in ambito SIP.
Prova a controllare il manuale del tuo specifico apparecchio ma se ben ricordo non è supportato se non su alcuni modelli Zyxel (che obiettivamente e personalmente sconsiglio comunque di impiegare in ambito voip)
