Hello all,

I am planing to deploy 2851 with Cisco Call Manager Express. But I am not sure what are the things I need  in order to deploy VoIP with 2851 router.

As far as my understanding goes.
1. Cisco 2851 router with S28NIPV (Cisco 2800 IP Voice) or Cisco 2851 router with S28NSPSK9 (Cisco 2800 SP Services K9)
2. VIC2-4FXO x 4 pcs (for PSTN connectivity)
3. FL-CCME-100 (IP phone licenses for 100 phones) x 1pc 
4. IP Phone CP-3911 (IP phones) x 50pcs

Please give me comment on above list, Am I missing something here?
Is  there any Voice bundle for Cisco 2851 with Call Manager Express?
What kind of licences are required to deploy VoIP with  Cisco Router?
What is the feature difference between Cisco 2800 IP Voice IOS  and Cisco 2800 SP Services K IOS. Where can I find more on IOS feature informations?

thank you in advance,
