Patent ID: 7567520

Claim:
A method of testing a VoIP network comprising: (a) transmitting from an originating endpoint on a VoIP network to a call management system (CMS) on the VoIP network a special mode sequence and a telephone number of a destination endpoint on the VoIP network, wherein: the CMS, the originating endpoint and the destination endpoint are each assigned a unique IP address on the VoIP network; and the CMS includes a mapping between telephone numbers associated with telephones residing at said endpoints and the IP addresses assigned to said endpoints, and each endpoint does not include such mapping; (b) responsive to the transmission in step (a), transmitting one or more messages from the CMS onto the VoIP network that cause the originating endpoint and the destination endpoint to establish a network connection with each other via the VoIP network; (c) after step (b), transmitting a message from the CMS onto the VoIP network that causes the destination endpoint to enter into a test mode corresponding to the special mode sequence transmitted in step (b); (d) transmitting on the VoIP network one or more data packets from the originating endpoint to the destination endpoint via the network connection; (e) receiving one or more of either the same or similar data packets transmitted in step (d) back at the originating endpoint from the destination endpoint via the VoIP network; and (f) comparing the transmitted and received data packets to determine at least one of network delay, jitter and packet loss.
