Manual Testing With osmo-dev
----------

With [osmo-dev](https://git.osmocom.org/osmo-dev/) it is possible to
build all Osmocom components for a full test network with OsmoBSCNAT,
and run the network on your PC. Set up the make directory as described
in osmo-dev's README, then build components with:

```
$ make cn-bsc-nat
```

Set up a network as described in osmo-dev's net/README, then put the
following in your configuration to let it run osmo-bsc-nat with one
virtual BSC, BTS and MS (can be used next to a real BSC/BTS/MS):

```
BSC_COUNT=2
BSC0_CODEC_LIST="fr2"
BSC1_CODEC_LIST="fr2"
BTS1_RUN_IN_OSMO_DEV=1
STP_RAN_IP="127.0.0.2"
MS_RUN_IN_OSMO_DEV=1
```
