Abstract:
A method of verifying the path connectivity of a communication resource that supports a call between a first node and second node, the call established through a connection broker located intermediate between a call server responsible for controlling the call and a switch assembly that routes the call, and wherein the second node is separated from first node by at least one switch assembly, the method comprising the steps of:causing the connection broker to be aware of a requirement to confirm the path connectivity of a connection between the first node and the second node;sending, over the communication resource for the call, a path verify-request message between the first node and the second node;detecting the path verify-request message at a respective node to which the path verify-request message was sent;at the respective node to which the path verify-request message was sent, sending the connection broker a verify-confirm message indicating receipt of the path verify-request message over the communication resource for the call; andat the connection broker, receiving the verify-confirm message else causing the connection broker to register a fault in the communication resource for the call.
