  This is new to me, I have a fax server using Receive Fax and gets way over 5 calls at a time.   [fax-in]   exten => s,1,Answer() exten => s,n,Wait(1) exten => s,n,Set(BASEFILE=fax-${CALLERID(dnid)}-${STRFTIME(${EPOCH},,%Y%m%d-%H%M%S)}) ;exten => s,n,Set(${LOCALSTATIONID}) exten => s,n,MixMonitor(/mnt/ramdisk/${BASEFILE}.wav) exten => s,n,ReceiveFAX(/mnt/ramdisk/${BASEFILE}.tif) exten => s,n,Hangup() exten => h,1,System(/home/asterisk/dofax.sh "${EMAILADDRESS}" "${FAXSTATUS}" "${CALLERID(num)}" "${....<snip>         From: asterisk-users-bounces at lists.digium.com [mailto:asterisk-users-bounces at lists.digium.com] On Behalf Of Danny Nicholas

   Hi all,        I realize that the application Receivefax can't handle with more than one fax at the same time. In a environment  with a lot of fax, some caller get the signal but the operation can't be completed.    Is  there a way to send busy tone to the second caller?

Something like this: -       exten => s,1,answer -       exten => s,n,AGI(checkstat.agi) - reset variable if receivefax died or hungup -       exten => s,n,Gotoif($[ "${FAXINUSE}" = "YES"]?byebye) -       exten => s,n,Set(GLOBAL(FAXINUSE)=YES) -       exten => s,n,receivefax -       exten => s,n,Set(GLOBAL(FAXINUSE)=NO) -       exten => s,n,hangup -       exten => s,n(byebye),playback(im-busy) -       exten => s,n,hangup    
Why can't receivefax handle more then 5 faxes at the same time?  Are you using the res_fax_spandsp.so or the res_fax_digium.so modules?  It was my understanding that the res_fax_spandsp.so did not have a limit and the res_fax_digium.so was the commercial offering that is based on a per channel license.  

Am I wrong on the res_fax_spandsp.so module is there a limit other than hardware performance?
