What is the problem, when VoIP Signaling works fine but there is no voice at all?

| When using NAPT on a SmartNode there is one global IP interface (with the public IP address) and one local IP interface (with the private IP address). The H.323 gateway must be bound to one of the interfaces since it needs to know on which interface it must send broadcast RAS messages for gatekeeper discovery. When the gateway is bound to the local interface (the one with the private IP address) then signaling with a gateway or gatekeeper in the public network works fine, but RTP packets (voice packets) will use the private IP address and thus voice will not be routed to the destination. Thus make sure that the gateway is bound to the correct interface (generally the global interface when using NAPT). | |
