If it is of interest...

If you can configure your Avaya as an E1, you could configure Asterisk
as an E1 and have 32 channels instead of 24. I've never done this, but
have heard it may be an option.

I'm not clear on exactly all this means, but it sounds like about 24 (or 32) 
lines in extensions.conf to map each channel to an extension and then 24 
(or 32) lines to map each extension to each channel. You could do this in 
just a couple of lines with some fancy pattern matching.

If you have many more channels or anticipate frequent changes or if you 
want the users to be able to change the mapping via a web page you should 
consider storing the mapping in a database and then accessing the database 
within the dialplan using an AGI.
