I have a customer with CCM 3.3(3) and an MRP blade with 16 port FXS. The faxes are plugged into the MRP and they use the MRP PRI. A client out on the PSTN cannot send a FAX to the local FAX machines. The local FAX machines can send to the Brother FAX machines but this is intermittent. Sometimes it works and sometimes it doesn't. Faxes in-bound never work. They did work a couple weeks ago but then stopped. Any pointers would help. I'm goin go to look at some traces and run some debugs on the gateway while the FAX is being transmitted.
