I have a new customer with a R2 100 ver. 2.44 that is having problems faxing through the switch. They are using PRI and the card is ver. 4.14, which is a new version card that I haven't seen until now. The fax is connected to a 2sli board. The problem is that when they fax through the switch the speed to send/receive is 75-80 seconds per page. On a pots line that they have there its about 20-25 seconds per page. Not sure what to try here as we have lots of customers that fax through samsung's with pri's and no problems.
