your post does not provide enough information to help you
i hav a 2801 router which has some ip phones connected to it, and i hav a call manager 6.x i want to interconnect these two in such a way that the call manager becomes a publisher nd the 2801 is the subscriber that is the 2801 will send the call records to the call manager...
ok, you can have the phones with either CUCM or CME, but not with both. in any case what you would need to use is CUCM + SRST
the terms PUB and SUB are only used in CUCM environments, not with CME.
there's plenty of material within CCO
since you're new you will need to start reading a lot if you really want to learn
