Trough comprehensive and complete call testing to verify sys- tem interoperability and to identify anomalies, I3MP learned three lessons about preventing each of the three aforementioned problems:
• No call: Ensure that the local session controller can handle the data packets by properly configuring the installed local session controller and session border controller.
• Failed call: Verify that the local session controller and ses- sion border controller configurations match with the DISA and vendor networks.
• No audio: Coordinate and collaborate with DISA to ensure that the local session controller and session border control- ler handle all AS-SIP protocols appropriately. Toroughly test
the system compatibilities operational.
TDM technology requires that each element involved in the call be installed, maintained and operated individually. AS-SIP tech- nology is a break from the past in that it is an integrated, not a stand-alone, solution. AS-SIP is an end-to-end communication
to ensure that it is fully

TECHNOLOGY RELIC
In all, I3MP decommissioned 26 cabinets containing Fort Leonard Wood’s old telephone systems, which were outdated and costly to maintain. (U.S. Army photo)
technology, and if any stage of the session call does not transfer the protocol, it fails. Terefore, all stakeholders need to under- stand DISA methods and procedures.
CONCLUSION Te lessons learned from this first TDM decommissioning at an Army installation within the continental United States demonstrate that the Army can transition to an IP-based voice architecture. In the coming years, I3MP will apply the lessons it has learned as it continues to modernize Army installations. Te end result is a new telephone solution that reduces the time to establish commercial service from months to weeks while eliminating the need to maintain legacy circuits and equipment, helping the Army win in a complex world.
