Cisco Systems, Inc. is an American multinational corporation headquartered in San Jose, California, that designs, manufactures, and sells networking equipment. Although Cisco was not the first company to develop and sell dedicated network nodes, it was one of the first to sell commercially successful routers supporting multiple network protocols.
Products from Cisco have been tested by Dialexia to operate with its VoIP IP PBX and softswitch platforms and applications. Tests made include inbound and outbound calls, call transfers, IVR interaction, and CODEC negotiation. In order to ensure interoperability, Dialexia certifies and supports only specific combinations of third party hardware and firmware.
