Seems to me at this point, unless YOU know of a technical reason why you 
should not upgrade, your best bet is to tell the client either to let 
you upgrade to the latest 1.4 version, or to get someone else to support 
them.
I can understand legitimate legal reasons they my not want to use a fax 
to email service, but to insist on continuing to use a broken version of 
asterisk serves no one. They don't have the services they want or need, 
and you get a black eye because you cannot give them what they want.

The customer is NOT always right.
