Fax problem on VG248

Hi All,

I have a strange fax problem. Usually this fax works well, but sometimes (2-4 a day) the other side gets an transmission error report, while my side receives the fax. Both Side have Canon faxes.

My side uses Vg248 with fax-passthorugh, receives the fax through a PRI , the other side uses Cisco 2600, with FXS module, BRI, and fax-passthrough.

can it be a configuration problem, or line noise?

On the incoming PRi gateway I use passthrough also.

The config:

dial-peer voice 103 voip

tone ringback alert-no-PI

Re: Fax problem on VG248

talk to TAC about this. there is a bug with certain IOS versions where a successful fax is delivered, but an error report is generated and sent back to the sender. This sometimes results in multiple faxes being transmitted to one side or the other.
