I decided to change the sources with longer variables, so things are consistent with smsbox. cfg.diff has also been committed.

One thing I noticed is that you committed my patch with vars using shorter names: src-addr-npi, etc, while the svn doc uses longer names for them: source-addr-npi, dest-addr-npi and so on. Either the source code needs correction to match the documentation or later is messed up :) 2010/7/10 Rene Kluwen <[email protected]>: > Right away I also checked in your ton/npi patch. > > == Rene > > -----Original Message----- > From: Victor Luchitz [mailto:[email protected]] > Sent: vrijdag 9 juli 2010 23:19 > To: Rene Kluwen > Subject: Re: smppbox code questions > > Yeah, I was thinking about this "hack" as well, but it's going to > create more problems than it solves.
