Customer had installed an OS500 R2 V2.48 installed Dec. 2005 with an 8WLI card, three WBS24 WAP's and WIP-5000M wireless handsets.

Can we upgrade them to the latest SMT-W5120 wireless handsets?

I assume we need to upgrade the software.

With an MGI card will an OS500 support the new WAP's and the new wireless handsets?

Thanks,
