I have a VG224 MGCP w/modem passthrough, and a RightFax server with a Dialogic TR1034+P8-8L analog card plugged into it. Occassionaly, we get a loop-current drop error which can cause a fax that is half way through transmit to stop and resend.
On the PSTN, I have a 3845 MGCP with modem passthrough with PRI's. I have no slips on the PRI's.
Has anyone run into anything similar?
