I know you guys may have thought this through already.. Nevertheless,just thought I should share it when it comes down to UC design,from an architectural perspective, no matter what vendor you will select at the end...
1) Solution maturity and service partner maturity:
The same question went back to Cisco 10 years ago - we had lots of scars on our back and so many lesson learnt when rolling out a "new" voip system. It does not matter which vendor.. End users are very much less forgiven if anything goes wrong on phone system, period. So the solution maturity, service partner capability and availability are always on top of our mind;
2) Redundancy, availability and scalability
Local fail-over, remote survivability , load sharing, etc.. How soon can the system recovery from a hardware component failure, a server failure, WAN outage etc.. How the system will scale is also a good question to ask.
3) Supportability
How this system will be supported, by how many players... once the voice system is into production, the supportability can make or break an otherwise seemingly flawless system. How the trouble shooting process will be streamlined, how the skills can be prepared from first line help desk to IT support, which vendor to call for escalation, how to determine which party is responsible for what etc etc.. All are very important factors..
4) Migration planning
How to move away from the PBX, how to support legacy stuff such as analog devices i.e. FAX and paging system etc...What dial plan to consider during and after the migration.. etc..
5) Dependencies on network, on bandwidth, on site facility, on Telco's
To make the transition successful, the dependancies have to addressed up front.. How the solution will be integrated to your data network infrastructure, what type of WAN bandwidth will be required, how the connection to PSTN will be supported, what about cabling, UPS etc..
We will touch base this afternoon on some of those points in our quick call.. But thought this list could be helpful in your own evaluation process....更多精彩文章及讨论,请光临枫下论坛 rolia.net
