T.37 offramp fax not working

Hi,

I have implemented onramp and offramp for my customer. Onramp fax is working fine but the offramp fax is not working. When we test with facsBridge T37 we do not see fax coming on CME router.

Router configuration is

Model: 2911

IOS: 15.4(2)T

I have enabled the mta and foip debugs but no logs are generated. But when I run the wireshark debugs on laptop on which facsBridge application is running, I see acknowledgement from router. But Microsoft fax application which uses facsBridge as modem do the retransmission 2-3 times and then give fatal error.

I am not sure if issue is with config or i am hitting bug. Please guide me how to resolve this issue.

one update...on wireshark i am seeing RST, ACK from router which means it is reseting the session...but could not find reason for that. i tired with app_faxmail_offramp.2.0.1.1.tcl and app_faxmail_offramp.2.0.0.0.tcl script, but results are same.

Below is config of cme.

fax receive called-subscriber $d$
fax send transmitting-subscriber $s$
fax interface-type fax-mail
mta send subject Fax from On-Ramp GW
mta send with-subject $s$
mta send postmaster administrator@xxxxsolutions.com
mta send mail-from hostname xxxxsolutions.com
mta send mail-from username info
mta receive aliases xxxxxsolutions.com
mta receive aliases smtp.gmail.com
mta receive aliases 10.1.30.13
mta receive generate mdn
mta receive generate permanent-error
