I understand your situation. It's also important to understand that a 
great deal of equipment, and many IP based phone services, say that they 
'support faxing' without really defining what that means. In my 
experience, few IP based systems 'really' meet the levels of reliability 
and compatibility that business customers expect from fax.

I cannot say with certainty that IP is giving you these problems but 
that's my hunch based on customer experience. One 'simple' test that you 
could undertake is to put a modern fax machine on one of your cisco FXS 
ports and then broadcast to it from another fax machine off site (many 
business class fax machines can undertake a multi-page broadcast). IF 
you then get problems you will have a very powerful argument for your 
management and the cisco support people.
