[cisco-voip] Verify which device and firmware have sccp v 20 support

Tue Feb 21 16:12:21 EST 2012

Lelio,

The document i am referring to is official cisco documentation:
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/rel_notes/8_5_1/delta/delta.html#wp1849900

Cisco ofcourse preserves the right to decide whatever they want made public.
however in this case, it shows that they are referring to the SCCP version
as the only differentiator, a comment in the documentation for reference to
TAC or Account Team for more info would be better,
Thus preventing this discussion on the forum, as i would have contacted the
right channels for this. (which i will have to do now anyway :-) )
Seeing there are some tricks to find out which version is actually used
when using a specific firmware version, why not publish this information,
in order to prevent every partner having to test which version is actually
implemented in the firmware?
I don`t see why this should be such a secret, if the SCCP version 20 is not
implemented in the firmware, then it simply is not available right?
If it is on the roadmap for a certain version of firmware, i understand it
is not published, but then please comment this in the documentation.
It makes it very difficult for us, to retrieve the correct information, if
we are pointed to something, which we are unable to verify.

Thanks,

Erik
