[cisco-voip] cm5.1 and 6.0 'SRs' on Cisco.com

[Wes Sisk]

Hi Justin,

5.1.2es will include a subset but not all fixes from 5.1.3.  Later 
5.1.2es will contain fixes that are not present in 5.1.3.  Unfortunately 
there is not a clear answer on the break even point.

The timing of 5.1.2es release was unfortunate in relation to the 5.1.3 
release.  However, there is a large customer base who would rather stay 
on 5.1.2es rather than do complete upgrade to 5.1.3 to avoid the 'new 
feature's that come with 5.1.3.

The release process is most akin to the 4.x SR process.
An 'es' is produced internally.  It is tested and distributed to 
specific customers for 4 weeks.  Provided not major issues are raised in 
4 weeks the es is posted to Cisco.com for publicly available.  Only 1 es 
will post every 4 weeks.  Previously TAC was distributing ES via the SFA 
process several hundred times per month.  Original release schedule had 
maintenance release on Cisco.com once every 8-12 months.  This 
significantly shortens the release cycle for those who need additional 
fixes beyond the base release.

The basic ES process delivers code that is compiled, built as an 
installer and minimally tested for install and service start.  There is 
significant testing and exposure difference between this basic es 
process and and the ES that is posted to Cisco.com.  The ES that is 
posted to Cisco.com actually receives more testing than the SR's of 4.x.
