[cisco-voip] Cisco Docs conflicts!!!!

[Wes Sisk]

Phone loads 8.4.x use SCCPv17.
Loater phones loads use even newer versions of SCCP which will 
experience the same problem documented in the defect.

8.3.x and earlier will use a version earlier thank 17 which IOS/CME/SRST 
can parse.  Those versions may have other issues but should not suffer 
from this specific problem.
