Can Receive FAX but Send FAX error

[ajjampura]

My Sonic.net FAX number is 4084092981. I received fax to this number. But, I got the following error on sending:-
"Faxing of Myfile.pdf to 1408600xxxx failed after 5 attempts.
Unknown Status"

Actually Destination FAX number received 5 times the same FAX.
Please look into this issue.

Thanks,

Ajjampura
