Testing voice-over-IP interoperability at ComNet 2001

By Betsy Yocom, Network World |  Networking

In Miercom's second scenario, a bi-directional communications path gets established between an endpoint or gateway to another endpoint or gateway through a gatekeeper. In the H.323 specification, the optional gatekeeper provides call-control services to the H.323 endpoints.

Endpoints used in the second scenario of tests included IP phones and similar devices.

In either scenario, once a call gets established, Miercom' s engineers ensured that the voice path was established in both directions, regardless of which product initiated the call. Miercom also verified that calls closed gracefully, so that network resources were freed up quickly and available to subsequent callers, regardless of which side terminated the call.
