When the number of concurrent fax licenses maxes out the call does not end with a busy tone instead it plays a message, "nothing recorded". This results in the fax machine not retrying again later. I modified the dialplan to play a busy tone instead of the recorded msg. Once I did that our fax machine retried sending the fax.
This is just for receiving
This is just for receiving faxes. When I talked about sending I meant from a physical fax machine in my lab.
ok so you want a busy tone if
ok so you want a busy tone if the ReceiveFax errors for licensing. I dont want to alter the 'nothing recorded' code too much.. do you know if the FAXOPT function passes information indicating this? We could do a simple gotoIF condition is true in order to play Busy(). Are you sure its Busy() you want to do instead of Hangup(17) .. which will send the correct 'busy here' message back?
umm you mean sending or receiving? Your subject talks about ReceiveFax but then you talked about sending. can you elaborate more?
