My team has used the ZT Technology Solutions Tier 3 DMS technical support services of for several years now, supporting our embedded base of Nortel legacy DMS-500. We were looking for a high quality and cost effective solution for long term support and found ZT to be an excellent alternative to the existing OEM.
ZT’s technical support people are highly experienced, knowledgeable and very responsive. ZT has allowed us to continue to maintain our legacy equipment while we migrate to our next generation switching platform.
We have been very pleased with ZT Technology Solutions and highly recommend their services.
