PS3, Line 616: osmo_sccp_simple_client2(void *ctx, const char *name, uint32_t default_pc,
Done
Having done this, I can no longer get
osmo-bsc to talk to osmo-stp using M3UA/TCP. AFAICS, osmo-bsc is actually using this API
and since this API is assuming the default transport protocol (SCTP), something is
definitely going wrong:
```

```
Note the `No unassociated ASP for m3ua, creating new ASP` line. This is despite I am using
the following configuration in osmo-bsc.cfg:
```
cs7 instance 0
point-code 0.23.3
asp asp-clnt-OsmoBSC-A 2905 0 m3ua tcp
remote-ip 127.0.0.1
role asp
transport-role client
as as-clnt-OsmoBSC-A m3ua
asp asp-clnt-OsmoBSC-A
routing-key 3 0.23.3
```
Any input is welcome. I'll continue investigating this.
