Since i have a dedicated DID for fax calls, i don't really need the fax detection. For this number i simply start the ReceiveFAX-Application and have some voodoo around it to name the file correctly. But if i do this, and look into the channel information from Dahdi i see that the fax handled flag is set to no. And this seems wrong to me. I have the feeling that the percentage of failed faxes is higher is this flag is set to no (or false, can't remember) ... Since i have a PRI connected to my Asterisk, i use the built-in fax detection of DAHDI. I have enabled it for incoming fax calls, in chan_dahdi.conf faxdetect=incoming The incoming call is answered and with an included Wait(4) the fax is detected and switched to the fax extension, where the ReceiveFAX-App is executed. Now the fax handled flag is set to yes and i am able to receive most of the fax calls. But i have massive problems receiving fax calls from certain people, especially from UK (i am in germany). I am not quite sure, if the echo canceller is automatically disabled if DAHDI knows that the call is a fax and the channel info doesn't indicate otherwise, since it says that echo canceller is active even if it says that it handles an fax. This is the reason why i was so happy to hear, that there seems to be the option to control the echo canceller with an dialplan app. But since this seems to be an Bristuff-only feature i am a little bit stuck.
