Summary:                    Message with SAPI other than CALL CTRL is discarded
Description: 
This message appears with 2 different brands of router, NETGEAR RT328 and
Allied Telesyn AR130. These same routers, when connected to a Jtec Switch
QBRM card correctly establish a call, without any configuration changes to
either router.

When attempting to use B410P in NT mode, as soon as inbound digital call
is attempted, console show this error (with pri intese debug span 3).
