I have just found out about and installed Elastix 0.9.2-4. I am so releaved at finding an alternative to Trixbox. I think it is much much better. Especially I am soo impressed with the Hylafax integration. I am facing a problem which has been posted before here. http://www.elastix.org/index.php?option ... SY%2FConge but has no solution there. At first the faxes was working on and off. Sometimes the fax extension would pickup and other times it would just hungup striaght away. I followed the Fax video tutorial to setup and went over my configuration more than once. The other fact is that it did work a few times.. its just that it does not work all the time. Is the a reason why the fax extension randomly does give Busy / Congestion? thanks in advance and thankyou elastix on a great solution.
