Quest’s Technical Service Center (TSC) commits to providing superior customer service with Avaya-certified expert engineers from 8 am to 5 pm. We also have an emergency service engineer available 24 hours a day, seven days a week.

We are committed to answering your call by a live person – not a voicemail or a list of prompts! We understand that your time is valuable, and want to help answer your question or resolve your problem as fast as we are able. We communicate with our customers via phone, email, or fax – whatever is best for our customers.

Quest is proud of the fact that we resolve 95 percent of all calls into our Technical Support Center remotely, within 24 hours from receiving and then generating a service ticket. We value your time, and our record for resolving tickets, demonstrates this to our customers.

Quest partners with you to develop a communications system that fits your needs today and expands easily to meet your growth and the demands of tomorrow’s technology.  Have questions about our technical support center, or need a quote?
