0x80000048 is a generic TAPI error (LINEERR_OPERATIONFAILED) that the TSP will spit back to Unity when MWI fails. MWI could have not worked for any number of reasons. Some of those reasons could include incorrect MWI dn configuration, CSS issues, etc...

I had this same error on my system which is v2.4.6 Searching around the postings led me to look at my dial plan to see if any other devices were using the same number as my MWI codes. That was close but not the real problem. It turns out that I had extended my interdigit timeout and unity was giving up before callmanager initiated the dial. That was the cause of my lights not lighting.
FIX: I modified my MWI codes on the "AV-Cisco Service Provider" in control panel by adding a # to the end of my codes which caused callmanager to dial the sequence now. After a reboot, everything worked fine.
