What would be the correct device pack that includes the phone types 7906 and 7911?
The 7905s are no longer available. The 7906 seems to be the replacement model.
The Device Package release 4.0(46.4) only includes the 7911.
I'm sorry to say the 7906 is not supported in CCM 4.0(2). Here are some references;
Q. What Cisco Unified Communications Manager release is required for the Cisco Unified IP Phone 7906G?
A. Customers are required to use the most recent version of each Cisco Unified Communications Manager for full support: Cisco Unified CallManager Version 3.3(5)SR2, 4.1(3)SR3a, or 4.1(2)SR1 for Skinny Client Control Protocol (SCCP) only; Cisco Unified Communications Manager Versions 5.0(2) and higher for both SCCP and Session Initiation Protocol (SIP) support.
Cisco Unified IP Phone 7906G
Supported in Cisco Unified CallManager Versions 3.3(5)SR2, 4.1(3)SR3a, 4.2(1)SR1, and higher using Skinny Client Control Protocol (SCCP); supports both SCCP and Session Initiation Protocol (SIP) with Cisco Unified CallManager Version 5.0(2)
Hope this helps! Sorry for the bad news, perhaps the 7911 is a better choice anyways :)
