Hi

I m using “sendfax” application in ASterisk 1.6.2.2

50% of time i receive error like “The call dropped prematurely” when i am sending a fax (while the remote fax device is connected and working fine)

Could you help on this?
Maybe could you provide sip.conf optimized for fax sendings ?

Thks very much
