Topic # 112813 21-Dec-2012 14:29 Send private message

I have an Asterisk box with a Atcom AX400 card in it with an FXO module. All incoming calls come to the line on the trunk card and then if that line is busy they step to some SIP trunks.

This line has just been enabled with faxability and is causing some issues for me. I think I have a small clue how to go about fixing this but just wanted some gurus to have a look over it first.

I think I need to add something in to dahdi-channels.conf so that it looks at the ringing cadence and then sends them to appropriate contexts. What I will do is send the normal ring to the zaptel context to give it a DDI and then the distinct ring will go to a context that goes no where until such a time the fax answers.

I know there is 'usedistinctiveringdetection' but don't really know what to put with it to make it here the rings.

Any help much appreciated.

From my vague memory of doing this back in 2005 or so you need something like;

usedistinctiveringdetection=yes
distinctiveringaftercid=yes # Specifically needed for NZ/AU
dring1=1,2,3
dring1context=foo
dring2=2,3,4
dring1context=bar

You will need to work out the 1,2,3 and 2,3,4 numbers yourself, Asterisk can generate them to show you on the verbose console when an incoming call comes in.

Just an update...
Added this to the dahdi-channels.conf file

usedistinctiveringdetection=yes
distinctiveringaftercid=yes

dring1=100,0,0
dring1context=from-zaptel
dring1range=10

dring2=249,221,189
dring2context=from-pstn-5565
dring2range=10


Works really well. At first in my from-pstn-5565 I just had wait for 30 seconds and then hangup. But of course it would put a loop on the line and stop the fax receiving. Luckily I had a station module for the Atcom card. Made the fax an analogue extension off the system and then made my custom context go to that extension.
I thought about just making the custom context assign a CID to the channel and then use an inbound route to send the call to the fax but wasn't sure if Asterisk would screw with it on the way. By sending it straight to the extension I hope I have done the right thing. Seems to all work well though.
