We've previously used h323 on all our vg200 gateways (both to the pstn on e1, and to fax machines using fxs and fax passthrough).... I've set up one using MGCP, but am unable to get a fax through it. Dial plans etc are ok, the call gets through, but the fax machine displays errors... config is as follows:

Much of the Cisco docs don't seem to apply to this IOS (12.2(16)) as the only fax related command I can find is " MGCP modem passthrough Cisco/CA"... i've tried both settings of this...
First off what type of errors are you talking about. When you try to fax something can you do a show voice port summary and verify that the port goes off hook. You can connect an analog phone to the same fxs port your fax is connected to and make a call? You might want to also try disabling t.38 with the command mgcp fax t38 inhibit
Thanks for your suggestions, however.... I can verify that the fxs comes off hook, dials ok etc... however the error I get on the fax comes from the fax itself and is a pretty generic "Comms Error".... We've had this before due to bad QOS and a few other issues, all of which have been checked out.
Standard phones work fine, and the mgcp fax t38 inhibit command has been dropped from this IOS version .... I'm going to try reverting to an older IOS today...
OK... according to the document referenced above (http://www.cisco.com/univercd/cc/td/doc/product/voice/c_access/fxmdmnt.htm).... The lowest supported IOS version for fax passthrough or fax relay is 12.2(2).... I've reverted back to 12.2(5) as the earliest IOS 12.2 I can find, but this still doesn't have any/many of the mentioned commands, and the faxes still do not work.
P.S. I just noticed your configuration has "no ip routing" in it. That is frequently the cause of one-way voice problems in voip networks and could be contributing to your problem. You might want to take it out.

The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
