I have an cucm6 with a 2821 as h323 gateway for the pstn (e1-cas r2). I solve the fax issue from the pstn to an fxs port in the 2821.
Now I have an 2811 router for the WAN conectivity. My cucm6 is connected to an gatekeeper (dedicated router) in a remote branch. At the remote branch there are others 2811 routers for the WAN connectivity and voice gateway to an siemens hipath pbx. There are fax machines attached to the siemens pbx.
When I try send a fax to the remote branch it fail.
I want setup fax pass-through between the cucm6 and the siemens pbx....
