fax losing pages

Unanswered Question
Feb 7th, 2007

We are losing fax pages intermittently and it appears that this is happenning when someone faxes from a Rightfax i.e from a PC Fax software similar to Winfax though we are still trying to pinpoint it exactly. It all was working fine and we have not changed the 2811 configs. Problem appeared couple of days ago.We have a CM cluster and the 2811 connects to a 30 ch PRI to access the PSTN and uses H.323 i.e no MGCP. I cannot see any slip etc errors on the serial interface.

Any help would be great. The faxes are coming from various external organisations via the PSTN link. Would the Call Manager be involved in such a fax call?

I have this problem too.

Check the controller stats, for slips or any errors on both the connection to RightFax and the PSTN connection.

Is call going over your network (not pots to pots leg in same gateway). If so, are you using FAX passthrough or FAX relay across the network between PSTN gateway and where the handoff to RightFax is?

Hi Eric,

Many thanks for the reply.

The calls are coming in vice the isdn (pstn) and going out to the fax machine via POTS dial peer to a voice port on a FXS card. I have pasted the config below:
