Cisco CME and IPHONE INFO

        Good morning,

I've     a cisco callmanager express 4.2 on cisco router 2821.

I need to upgrade it to a new CME version.

I need to connect to  the CME more Iphones.

Which version of IOS  (or CME) support this feature?

Actually I've a 12.4.3 IOS version.

To upgrade IOS is necessary to open a smartnet?

thanks in advance

regards

Giancarlo

Yes you need to update.

However since your router is very old, no support contract can be purchased anymore.

You best approach is to engage a reputable consultant, or UC certified Cisco partner, and let them resolve all the issues.
