Hi list! I'm using bristuff on a box with one BRI line. I have echo cancel on. However incoming faxes (which routed to a Sipura 2000) fail after about 2 pages and the fax will report a communication error. I switched off echo cancel but ofcourse now I have an extremely annoying echo. Is there anyway to differentiate and switch on/off echo cancel depending on the type of communication? Adding another bri line just because of this is not really an option. Thanks! Remco
there is an application in bristuff that lets you selectivelly turn off echo cancellation for a call. Use that one for all fax calls :) On 4/14/05, Remco Barende <asterisk@barendse.to> wrote:> Hi list! > > I'm using bristuff on a box with one BRI line.
