[cisco-voip] sccp registration if IOS router left at sccpkeyword version 4.1

Thu Jun 10 09:58:03 EDT 2010

That makes sense - I have quite a few SCCP controlled conference bridges
still using the 4.1 keyword with CUCM 6.1 that we have not got around to
changing yet.  These are working with no problems  In a perfect world
you would have all of your routers/gateways on the latest IOS and
co-ordinate changing the config with your upgrade. Unfortunately this is
not always practical.

If i am not mistaken, 

the (ccm) version keyword in IOS is used by the router to determine the
Skinny version used to register with CCM.
As such a CCM v7.1 can very well understand its own skinny version and
all previous skinny versions.

That being said, an incompatible bug fix / enhancement is what causes a
new skinny version to being added.
so its generally recommended to be on the latest SK version.

It wouldn't. 

Basically with the sccp version mismatching you can expect one of three
things to happen.
1. No dspfarm media resources will register.
2. They will register, but calls will fail.
3. They will register, some calls will work, others will fail in
strange and unpredictable ways. 

This one is guaranteed to happen every time.
4. TAC will yell at you to upgrade your IOS.

But this is for conferencing and transcoding, how would that impact the
7965 registration process?

What happens if a router is left running with keyword version 4.1 but
you upgrade Callmanager to 7.1(3b)SU2 ? I can’t seem to tell a problem,
it looks like conf and transcoder stay registered, but surely there must
be a reason the keyword got updated, etc.

Older verion IOS 2811
sccp
sccp local fastethernet0/0
sccp ccm 10.10.55.133 priority 1 version 4.1
sccp ccm 10.10.55.132 priority 2 version 4.1

Once you upgrade to 12.4.15 or higher you get keyword 7.0+
sccp
sccp local fastethernet0/0
sccp ccm 10.10.55.133 priority 1 version 7.0+
