I'm not holding out any hope that NEC will change anything. Support told me as much, and if they aren't using standards that others can use, well, . . . I'm hoping that Eventide will come through.

Support mentioned standard sip phones too. Don't really want to go down that rabbit hole. New install, lots of phones that should be recorded, etc. More expense on the job that just keeps on taking. :-)

Just venting now. Thanks for listening. Let you know what develops.
