Hello all! I have a trouble. I have a   server mcs 7816 CIS-MCS-7816-H3-IPC1 and CallManager 4.3 CIS-CM4.3-K9-7816-H3 / SW  Only,  Unified CallMgr 4.3 For MCS 7816-H3, 300 User on it, and 300 user licenses. I want  to  upgrade my CallManager to 7.1 version. What software and license i must  buy for  this upgrade. Please help. Thank you.

The ordering guides document this quite well: http://www.cisco.com/web/partners/sell/technology/ipc/uc_tech_readiness.html#~7

Thank you, Jonathan! But could you exactly tell me what software i must buy for upgrade? Ordering guides not accesible for me.

No sorry. There are too many variables that can influance what SKUs need to be ordered for me to accurately address this here. Ordering guides are accessible to authorized Cisco partners whom you have to order through anyways. Work with your partner to assemble a bill of materials.
