Very stable phone system for the uptime requirements of general office environment. Occasionally we have needed reboots, but the failover between call managers typically happens within 10 seconds, and calls in progress are not affected. Handsets are extremely durable. Ours are about 6 years old and I would guess that less than 10% have failed. Administration tasks are also relatively easy to perform. Our previous PBX was difficult to maintain and required a lot of outside vendor support. Administration on our Cisco system is nearly 100% in-house. Review collected by and hosted on G2.com. What do you dislike about Cisco Unified Communications Manager (CallManager)? The licensing model is not giving out any freebies. You will pay for everything. You will find many budget minded IP phone systems on the market. So if price is the primary concern this is not the PBX for you. But when compared to the other established PBX manufactures this system was competitively priced. The failover between handsets is perfectly adequate for an office environment, but in a high volume dispatch center the failover time is not always adequate. In our case we have a few dispatchers that have a large number of phone lines. Due to the large number of lines these phones can take a while to failover to failover (in the event of a reboot or PBX failure). To work around this we do our best to schedule reboots and upgrades during hours of low call-volume. All this to say that at least in our configuration this system is not fault tolerant. So if you have individual handsets with extreme uptime requirements be cautious and verify this system will meet those requirements. Review collected by and hosted on G2.com. Recommendations to others considering Cisco Unified Communications Manager (CallManager): Cisco isn't the cheapest solution. But it's been very stable and provided exactly what we need. Maintenance has been very minimal. Review collected by and hosted on G2.com. What problems is Cisco Unified Communications Manager (CallManager) solving and how is that benefiting you? Replace our End-Of-Life existing PBX with a solid and reliable PBX for a reasonable price. The Cisco unified communications system has provided the price and reliability we needed. As an added bonus we have moved all routine administration in-house which has saved money and allowed us to respond more quickly to our user's phone service requests.
