Routers Incompatible with SIP (VoIP)

Routers Incompatible with SIP (VoIP)
 
Your router might not be compatible, for various reasons, including, perhaps it won’t allow phones to register, cannot disable SIP ALG (Application Layer Gateway), or does not have a properly configured QoS. It is more likely that you will have a problem if you have a modem and router in one.
