I've not implemented any form of channel bank with *, so can't offer much
help on specific vendor/models. Since there are a fair number of folks
using them on the list, try posting a new thread with channel bank in
the subject, and summarize the responses in the wiki.

Personal opinion is that throwing a channel bank at * (other then for
better echo cancellation on trunks) is like taking a shower with your
socks on; don't see any practical use. But, I'm sure some do.
