Hi,
the call is established and the communication between sender and receiver start, but fails on modem training. This only when my pbx receive faxes.
When send all is ok.
For example, on same server if I send a fax from hylafax to extension on B400P card I receive
"FaxSend[5407]: SEND: Failure to train remote modem at 2400 bps or minimum speed; Giving up after 3 attempts to send same page "docq/doc13.ps;c1", dirnum 0".
This also when receiving fax from external line. I want repeat that when send all works fine.
between E1 trunk (where is the fax caller) and BRI extension (where is the corporate fax server).
E1 is on DE130E card in te mode, BRI extensions are on B400E card in nt-mode (ptmp). On corporate fax server there is an AVM ISDN Controller C2 in te-mode (ptmp).
If you tell me "seems you are bridge the call from another line interface", I ask you if the is correct or wrong.
