I have a SL100 telephone switch with call pilot server Version 2.50. I am located on an Air Force Base. Mysteriously last Friday 7/27/12 the call pilot stopped transferring calls to my DSN(Defense Switching Network) trunks. It transfers calls fine to on base numbers and to the local city trunks. For some reason on the DSN trunks the call just drops and you get a fast busy. I don't know if the transfer is not completing or what. Any ideas?
