[Asterisk-Users] 5 Channel / Trunk ??

[Brian D Heaton]

Steven is right.  Making them all 2-way DID trunks will greatly simplify
your routing.  Inbound can be on whatever order the LEC wants and your
outbound can be the same.  It will be a bit more expensive, but it will
save headaches.

You'll probably want to keep an eye on the CDRs to see how often all 5
trunks are busy.  That (and reports from folks attempting to call in)
will be your first indication that you need an additional trunk.  If one
of the 3 companies it making majority use of the trunks you can see that
too.

This will also allow you to get a block of say 25 DID #s and have not
only customized auto attendants, but also individual company fax
numbers, etc for each company.
