[asterisk-biz] Foip solution

[Rob Rothberg]

That was really the issue. I had zero control over the recipient. It  
was not uncommon for an end point to be using a 15 yo fax machine.  
Someone else above mentioned 95% Success. That might be ok for many  
but for us that would have meant dozens if not hundreds of faxes a day  
didn't make it.  Hopefully there is enough info here now for the  
original poster to understand the issues and decide if t.38 is for him.
