asterisk users - Jun 2006 - Asterisk + Linksys PAP2-NA / Call Clearing

I have a handful of Linksys PAP2-NA's all talking nicely to Asterisk using
standard telephones.  I've been running them for the better part of this
year.  No complaints whatsoever.  We chose the PAP2-NA's mainly due to cost
and especially the ease of provisioning.

In an effort to inexpensively bridge our office PBX (InterTel Axxess) to our
VoIP network, we've opted to connect PAP2-NA's to the InterTel as we met
with nothing but failure trying to get the InterTel to talk directly to
Asterisk (InterTel problem, not *'s - SIP on the Axxess platform is broken,
and MGCP doesn't seem to be compatible with *).

The problem I'm having now is with call clearing when the remote end hangs
up first.  I'm not sure if what I'm seeing is an Asterisk or Linksys
problem.  When I terminate a call locally, the call clears fine.  When the
remote-end hangs up the call, the PAP2-NA does nothing - no hookflash, no
dialtone, nothing.  Eventually, the PAP2-NA bursts out a fast-busy at you.
The PAP2-NA will tell * "Busy Here" if another call comes at it while
it is
in this state.

Has anyone run into this, or have suggestions on how to troubleshoot further?
