It looks like something wrong in your network.yml file.
Your /etc/ngcp-config/network.yml should look like:

      hwaddr: 08:00:27:c2:82:aa
      ip:   <------- you voip IP
      shared_ip: []
      shared_v6ip: []
        - web_ext	<---- service on eth0
        - sip_ext
        - rtp_ext
        - ssh_ext
        - mon_ext
      - eth0
      - lo
      hwaddr: 00:00:00:00:00:00
      shared_ip: []
      shared_v6ip: []
        - sip_int
        - web_int
        - ha_int
      v6ip: '::1'
      - proxy
      - lb
      - mgmt

make sure of that and run ngcpcfg apply.

As above.

There are no codec to configure on SPCE. It's not a B2BUA. The codec are
negotiated by clients. So if you have client supporting codec g729 you
can talk with g729.

Just setting up a SIP Peering. All calls getting from that SIP Peering
will be managed by SPCE as "Call from PSTN". Also SIP Peering will be
used for outbound calls. The documentation is quite clear here.

What do you want to achieve exactly ?
If you want to set a SIP Peer only for inbound calls you could avoid the
outbound call on this peer using the its SIP Peering Group/Peering Rules.

You can apply NCOS on Domain level (all subscribers within the domain)
or on Subscribers Preferences level. The NCOS will be parsed before to
go to the outbound gateway.

CDRs are stored into mysql DB (accounting.cdr) and the system exports
CDR into CVS text file under /home/jail/home/cdrexport/.
