The only sugestion is to patch the ss7 reset function in chan_ss7, because it's broken like that forever, despite
what people will tell you ;-) The patch should be pretty straight forward, as all the parameteres are sent correctly
(according to the specs). The problem lays in the cli parameter parsing to the right MSU values.

Btw, the remote switch should not ignore such a CGB, only CGA it and block the CICs that are available (defined) within the specified range.
