I have the following:
(3) DSP 64 chips
(1) PRI
(1) FXS 4/did card
There is something goofy with this new "Version" on SCCP commands.
If I use version 3.1 on my SCCP, My CFB and xcode works fine, but my MTP will not register.
If switch to Version 6.0 for SCCP, my MTP, but then CFB and xcode will not register.
12.4(22)T2 is on the router.
Its a basic config.

sccp ccm XXX.XXX.XXX.XXX identifier 2 version 3.1
sccp ccm XXX.XXX.XXX.XXX identifier 1 version 3.1

I hunted the bugs, cant find anything.

Ok, can anyone tell me why this configuration works? notice the versions are different for MTP and xcode and transcode CCM? But this is the only way I could get it to work??

I love a thread I an answer myself, that I started.
So...... After CUCM 5.x, it only uses Enhanced for Transcoders and Conference bridges.
MTP by default uses Enhanced, no other option.
So when I configured SCCP Version 3.1 with standard bridge and xcoder, it worked fine.
But in SCCP 3.1, MTP was not introduced yet in CUCM.
This is why MTP worked with 7.0 or 6.0 or whatever.
So, changed the bridges and xcoders to enhanced, then changed my versions in SCCP to 6.0 and everything worked.
It throws you off because 3.1 actually works fine with standard in CUCM. but if you require MTP, everything has to be enhanced.
Enjoy
