[Spce-user] LCR not working

Hi all,

I'm having troubles setting up Least Cost Routing in Sipwise, LCR isn't
working although all config settings are in place I guess.
The calls are working trough each peer, but the fees are ignored and
it's balanced between the peers.

I'm using CE version 3.7.2.

lcr is enabled in /etc/ngcp-config/config.yml:
max_gw_lcr: 128
perform_peer_lcr: 'yes'

I've added 3 different Peering Groups, with the same priority. Each
peering group has a Billing Profile. They have only 1 Fee Entry, with
the same source pattern: .
The destination is ^31
The only difference between them is the onpeak follow rate and offpeak
follow rate: peer 1 has 0.1, peer 2 has 0.2 peer 3 has 0.3
The intervals are 1.

Peering Server:
Each Peering Group has got a single peering server, with weight 1. They
all have a single peering rule with an empty callee prefix, callee and
caller pattern.

I can tell that LCR is enabled, because I placed some debug lines in the
config file, /etc/kamailio/proxy/proxy.cfg, in
# re-order lcr list based on costs per peer-group

A strange thing, dunno if it's relevant, but in the kamailio.lcr_rule
table there are only three records with an empty prefix, and NULL for
request and from uri:

mysql> use kamailio; select * from lcr_rule;
Database changed
| id | lcr_id | prefix | request_uri | from_uri | stopper | enabled |
group_id |
|  3 |      1 |        | NULL        | NULL     |       0 |       1 |
     1 |
|  4 |      1 |        | NULL        | NULL     |       0 |       1 |
     2 |
|  5 |      1 |        | NULL        | NULL     |       0 |       1 |
     3 |

When calling, an error is shown in the proxy.log file, a snippet:
NOTICE: <script>: Call to SIP Peering -
R=sip:316<SNIP-DESTNR>@<SNIP-HOSTNAME> ID=1540068188-268_b2b-1

WARNING: <script>: Failed to load dispatcher entries for lb using did

I can't tell what I'm doing wrong or how to troubleshout any further..
Normaly, I would check the lcr_rule tables, but these are empty. I don't
know how lcr works with the sipwise patches on Kamailio.

Kind regards,
