Gateways are telephony endpoints that facilitate calls between endpoints that usually would not interoperate. Usually this means that a gateway translates one signalling protocol into another (e.g. SIP/ISDN signalling gateways), but translating between different network addresses (IPv4/IPv6) or codecs (media gateways) can be considered gatewaying as well. Of course, it is possible that multiple functionalities exist in a single gateway. |
