You may want to ask on the cisco-voip list as it=E2=80=99s most =
centrally focused on that.
Do you mean with CM or CME (as suggested in your subject line?)
We have generally been abandoning the Cisco devices as they haven=E2=80=99=
t released an =E2=80=98open=E2=80=99 phone in many years outside of what =
you mentioned, sipura/linksys. I=E2=80=99m similarly looking for a =

doesn=E2=80=99t require CM, handles being behind NAT/nat traversal =

We have been provisioning PAP2T for people who need the single ports and =

directly to someone.
