CRITICAL

“Basic offering, very cost effective. Too many faults in UC soft client”

3.0
Dec 22, 2017
System is not particularly feature rich and many things that seem like faults are classed as the design. Unified Comms soft client is very poor, many faults are not resolved and the latest layout in V7 is confusing for users. Our experience has been that desk phones are the best option, they are more reliable and users generally feel comfortable with them. Contact Centre aspect of the offering is very good. Very few outages since go live have been caused by the software. Email integration is basic and under-developed, this is the weakest part of the solution.

    Overall OSV install went well. Genesys install was performed by several different vendors supplied programmers because of our short timelines. Because of this it is difficult to self-maintain the call flows.

    The vendor was Siemens when we started and then went to Unify and now ATOS. They had more field employees back when we installed this. Their support is still strong as long as you are willing to work with folks remotely. Their support staff does know the product. Implementation went well with all personnel coming to our site for each install piece. We have since upgraded all applications several times both remote and onsite . We have very little product issues.

    Quantum leap from a 22-year old legacy Rolm system to 2016 Unify 4th Generation VoIP

    4.0
    May 8, 2017
    Overall Unify was able, through the prime contractor Arrow Systems Integrated, deliver a working system. We have deployed about 15 servers at our main datacenter in Los Angels and an active backup node with 8 servers 60 miles away in Riverside county. It took a year time to design, engineers, procure, install, test, and commission the system. We have about 5,000 phones (3,000 VoIP and 2,000 analogs) to deploy and we have completed about 20% of the deployment. We are geographically dispersed across 60 facilities across 5,000 square miles.
