Just updated opensmppbox with the following log message:
2012-12-11 Rene Kluwen <rene.kluwen at chimit.nl>
Reverted back to v63 due to too many bugs and problems in these
sources.
At the same time, introducing a new ESME-to-MT routing possibility.
See documentation about 'smsc-route'.
Users that currently rely on the MO-routing patch are encouraged to
use bearerbox's 'smsbox-route'
in combination with 'use-system-id-as-box-id'. It works exactly the
same.
The "old" opensmppbox is still availabe as a branch called
"single-bearerbox-connection".
You can still check that branch out if your software is relying on
it.
