You are in fact correct.
I didn't have a router in front of me and wasn't thinking of that.
If fact what I was thinking about somewhere in my brain was the
ability to have 1 PRI timeslot group - and dynamically carve half of
it up for Voice and half of it up for Data - but that isn't at all
what you are trying to accomplish.
So that being the case - you have 2 options:
1. Configure each set of timeslots as a DS0 CAS trunk and not a PRI
or
2. Configure one whole PRI using MGCP and create the GW in UCM - and
have the telco send you in calls from one direction (i.e. bottom up)
and you send calls out the other direction (i.e. top down).
This way even though all of the Bchannels are in one PRI - you are
pseudo allocating Bchannels 12-23 to inbound calls from the telco and
pseudo allocating Bchannels 1-11 to outbound calls from your
organization.
Any reason you can't use CAS for this as in option 1?
This is a typical thing for CAS but not for PRI.

Mark and all,
could you please explain how to configure multiple groups of
timeslots, on one controller? I have tried to configure it, but as
soon as i want to configure the second time-slot group i get the
following error: %A ds0-group was configured already. Please remove
it to configure a pri-group. I am using an E1 Controller for PRI and
IOS Version 12.4(5)c.
My configuration is as follows:
isdn switch-type primary-net5
controller e1 3/0
pri-group timeslots 1-3,16
And after i enter, pri-group timeslots 4-5, i get the above
mentioned error. I think this can´t be configured because the D-
Channel is bound to the first pri-group and that the D-Channel can´t
serve more than one pri-group.
Is this correct?

Kapil is correct as far as CAS MGCP circuits go.
I am sorry - but I was under the impression that you were strictly
asking about a PRI config with MGCP.
If you wanted two PRI timeslots - one used in outbound and one used
in
inbound only direction - set them both up as h323 (i.e. two pri-
timeslot commands without the 'service mgcp' at the end). H323 can
handle that problem all day long with no issues (bugs or otherwise).
