Faxing from MAPICS at remote locations

We have some offices in foreign countries that want to be able to fax 
MAPICS PO's and COM orders.
We have implemented a solution on our iSeries that uses an external modem 
or can email a PDF document.
The problem is that for the foreign offices it will be an international 
phone call to fax using the iSeries modem.

The solution I'm considering is set up a local fax server at the foreign 
location. We could then "print" from the iSeries to 
the fax server and have it fax the document OR use email and fax the PDF 
attachment.
The print stream from the iSeries would be PCL output.

Anyone else implement something like this?
What fax server software did you choose?
Any other suggestions besides replacing our current fax package?

Thanks
