Hi,
Good to hear about the progress.
Would be really great If you can solve this MTP2 problem and merge to
the trunk.
My boss asked us allready to switch the two lines from libss7 to the
commercial ss7box (Sangoma) we also use for other carriers. Would be sad
(and expensive for several reasons) to do so...
Regards,
Erik
