Here is a great fax troubleshooting doc on the Cisco site:

I had some intermittent fax issues with a MGCP controlled  VG224 also. 

The command "no ccm-manager fax protocol cisco" seemed to helped with
the intermittent receiving fax issues

We upgraded the mem on the VG224 so that we could run a new IOS and
address a TACACS bug. 

Currently have IOS vg224-i6s-mz.124-8.bin.

Here is part of the config that seems to be working ok for us now.  

Any suggestions for improvements are welcome:

Check out CSCse13526 ,it gave us a lot of pain to get this bug openned
with Cisco.but this is definetly something which you could be hitting in
4.1.3 ,fix was rolled out in es 58.Also do you have FXS ports
unregistering a lot.

Hello, 

I have the following setup PSTN->2821->VG224->Fax Machines with VG224
configured for MGCP (IOS 12.4-2.T3, CCM 4.1.3) 
and fax pass-through. 
Users are constantly complaining about problems sending and receiving
faxes. 
I have noticed that the FXS ports on the VG224 are off-hook, while the
fax  machines connected to these port are idle 
and the RTMT shows that the FXS ports are idle. With a port reset the
problem is solved. 

Can anyone please suggest an IOS version to use for VG224? 
Is SCCP configuration preffered over MGCP? What about fax pass-through
versus fax-relay? 

Any comments would be appreciated. 

Regards, 

Evi
