[Asterisk-Users] is it possible to force faxdetect / disable echo cancellation for a given extension?
I have the newest SpanDSP setup with asterisk 1.2. Generally, 99% of received faxes are OK, but only about 20% of faxes sent are delivered properly. In zapata.conf I have set faxdetect=both, but it doesn't seem to disable echo cancellation (I looked into asterisk logs and it says "Enabled echo cancellation on channel 1, Engaged echo training on channel 1" whenever I fax out). Why doesn't asterisk detect that it's faxing? So my idea was to disable echo cancellation whenever fax number is called: exten => 27229932,1,Answer exten => 27229932,2,DISABLE_ECHO_CANCELLATION exten => 27229932,3,Goto(in_fax,1) (...) And do the same when I sent faxes using .call files: OPTIONS: DISABLE_ECHO_CANCELLATION Channel: $CHANNEL/$FAXNUM MaxRetries: 1 WaitTime: 20 Application: txfax Data: $DATADIR/$ATTNAME.tif|caller Is it possible to do something like that? -- Tomek http://wpkg.org WPKG - software deployment and upgrades with Samba
