Your call could not be completed because the call was routed through an intermediate network that does not service the far site. Contact your network administrator for assistance.

Most likely Cause: Firewall or Router access list blocking the H.323 messages required.
If there is a gatekeeper involved the unit may not be registered properly.

To alleviate the problem of IP dialing, the H.323 standard defines the use of a gatekeeper.
The gatekeeper is a system that connects to the Internet just like the client terminals. The IP address of the gatekeeper is configured into the client terminals and when the clients “power up”, they communicate with the gatekeeper and transfer certain information to the gatekeeper that describes the vct.

  1. Another reason for this error is that you are not actually calling a vidconf node. A common example of this problem is a site where the vidconf unit is on DHCP rather than a static IP and it loses the lease to the IP – you end up calling a desktop and get the “Your call could not be completed because ..” message.

    If you get this error it is always worthwhile checking ‘what’ is listening on the IP you dialed by contacting the endpoint VC administrator or by using several endpoint identification techniques (telnet banners, http response, nmap OS fingerprint, etc.)
