[Asterisk-Users] T100P to Merlin Legend - Using only 8 B-channels?

[Brian McSpadden]

Yes, it should, as you may define in zaptel and zapata which channels
are B channels, and which ones are D. You will just have to figure out
which channel the Legend is putting the D channel. It will probably be
either 9 or 24, but it is hard to say which, knowing Lucent.
