Fax Machines - VG224

Fax Machines - VG224

(OP)
Hello,

I'm having one heck of a time getting fax machines to work. What works at one site doesn't seem to work at another. They are all connected to a VG224, through VG Router that uses a SIP Trunk back to the CUCM. The fax goes a out a PRI and the VG224 is MGCP using t.38. Faxes fail to receive. When I call the fax from a regular phone the fax connects but then drops right after connecting. Ideas? Thanks
