[hylafax-users] EOP problems with t38modem and Cisco 5850



We are attempting use hylax, t38modem, & Cisco 5850's for outbound faxes but with certain fax machines we are seeing issues where after the EOP message the far end seem to results in a Line Error and fax fails. We can take a difference fax machine on the same line and have successful transmissions every time. The interesting thing is that if I fax a document that is 3.85 line/mm the fax seems to go thru to any machine but when 7.7 line/mm fax is sent only certain fax machines will accept it. The results are very consistent and are reproducible.
 
Thanks in advance for any insight any might have!
 
I am running t38modem with the following options:
 
/root/t38modem/obj_linux_x86_r/t38modem -n -o trace.log -p/dev/ttyx0 --old-asn --h245tunneldisable --route all@xxxxxxxxxxxxxx -g xxx.159.69.101 -u hylafax2 -tttt

This is one of the failed traces:
