we are experienced a problem with receiving fax, sometimes we receive half page, the fax call come from PRI to FAX connected to FXS port.

the following if for the incoming Fax calls

voice-port 0/0/0

station-id name FAX-001

station-id number 046993199

caller-id enable

dial-peer voice 2001 pots

destination-pattern 199

fax rate disable

port 0/0/0

Note : The problem was also with ATA 186 , I replaced it with FXS port but still the same.

Can you get 'sh controller e1' off the PSTN gateway?  Also get these outputs off both gateways:

sh call history voice br | i lost

sh call active voice br | i lost

Also, ensure that you have modem-passthrough configured on both devices.  Post both configurations if you are unsure if that is configured properly and I can verify.

You've got slips on your E1.  That will cause fax failure every time the clock slips.

Configure:

network-clock-select 1 e1 0/3/0

Then 'clear counter's and make sure all E1 circuits run clean.  Monitor fax reliability after this.
