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.
