Hi,
You have two approaches.
Option A
Use CCA to configure the unit from scratch. Configure the unit for your ISDN connection and test using the fxs ports. Manually configure a SIP dial-peer to route inbound PSTN calls to your Lync server. You'll need to tweak the configuration at various places to make it work. You therefore need to be pretty confident in understanding all the work CCA has done for you. The benefit this, is you have a local outbound dial-plan pre-configured on the unit.
Option B
Configure the unit yourself from scratch. Rough outline:
1. Configure E1 controller for voice
2. Setup the DSP modules for your region
3. configure a pots inbound dial peer to accept calls from the PSTN
4. configure an outbound SIP dial-peer to send the calls to Lync.
Lync expects calls to be prefixed with a + & E.164 and bare in mind the telco may only send you the last 6 sigits of the called number
Here's an example for UK ISDN with 30 timeslots: note module slots will be incorrect in this code, example is generic IOS and not specific to UC560.
1. Configure E1 controller for voice
!
card type e1 0
network-clock-participate wic 0 ! something like this, you may need to work out which slot you have
network-clock-participate slot 1 ! or something like this
network-clock-select 5 E1 1/0 ! you get the idea....
!
controller E1 1/0
pri-group timeslots 1-31
!
interface Serial1/0:15 ! do a show run to check the right interface slot number

2. Setup the DSP modules for your region

3. configure a pots inbound dial peer to accept calls from the PSTN
I suggest at this point, you debug isdn q931 and dial in. See how many digits the telco sends you.
Configure a number translation to put this number in to E.164
In my example we take the 6 digits the telco sends us and prepend 441234
voice translation-rule 10
rule 1 /^\(.+\)$/ /441234\1/
!
voice translation-profile incomingisdn
translate called 10
!
in exec mode:

description Inbound POTS dial-peer

4. configure an outbound SIP dial-peer to send the calls to Lync. Lync expects calls to be prefixed with a + & E.164 so we're going to add a plus

!
and that's about it apart from getting the fx0 ports sorted - one step at a time.
For outbound you added an incoming SIP dial-peer and an outgoing pots dial peer.
