[cisco-voip] Large deployment of IP Phones

[Fuermann, Jason]

Your deployment sounds extremely similar to ours. I don't have the exact plan we used, and instead of upgrading we did a new install and migrated existing voip users.

0.
Planning and meetings. This has to be everyone's least favorite part, and it took us the longest.
5 months
1.
By day, build test system and work out dial-plan and exchange integration, test odd devices (such as faxes and fire-alarms), document
By night, roll out new switches/rebuild closets
We did this for ~4 months, pretty much a closet per night or every other night
2.
Build new production cluster from documentation and verify correct operation.
This took maybe two weeks or so, mostly for the verifying.
3.
Develop bulk loads for roll out based on schedule, existing voip users are the first/easiest to move.
Roll out took us ~1 month

At least that's the way I remember it, and like Scott said YMMV. Now you have us all reminiscing on the good old days of overtime on 80 hour weeks.

Depends on man power, time lines, budget, and hardware.

my order of operations would be upgrade CM / hardware.

integrate Exchange UM

upgrade switching / routing infrastructure

deploy phones. Building by building or floor by floor.  depending on current configuration and how much you want to spend on updating dial plans on your PBX(s) doing the phones quickly may be your best bet.

YMMV

Hello gang,

Our CFO finally agreed to fund our IP Telephony project to decommission our old PBX and replace 3,500 legacy phones with IP phones. I've been working on the justification for more than two years.

I would like to know if any of you would know where I can find or have a deployment plan to rollout a project like that.

I already have about 1,800 IP phones on our current cluster. Our MCS servers are old and must be replaced (with Cisco UCS servers) and will be upgrading from 7.1 to 8.6 at the same time. We're replacing all our network switches with PoE switches and putting all voicemail on Microsoft Unified Messaging.

I just want to make sure that the rollout goes well since all of Upper Management (CIO, CFO and CEO) will be keeping track of the progress and know if things go very bad.

I'm looking for any info on the planning, deployment and support. By the way, we will be getting some professional services by our Cisco gold partner but I still need to make sure I have everything covered.

Thanks.
