<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I added an ast_channel_state(ast) == AST_STATE_UP test to this so the dialtone scanning timer will start running after the line answers. I also updated the chan_dahdi.conf.sample documentation to reflect this.
This makes it easier to figure out how long you should configure the line to look for dialtone.</pre>

This adds an option to chan_dahdi.conf called dialtone_detect. This can be set like this:
dialtone_detect = yes ; Watch for dialtone for 10 seconds after answer
dialtone_detect = always ; Watch for dialtone for the whole call
dialtone_detect = 5000 ; Watch for dialtone for 5000ms
If dialtone is detected on an inbound call, Asterisk will hang up the channel.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This patch has been installed on an Asterisk box connected to another Asterisk box simulating an upstream carrier. Testing was done with dialtone_detect off, set to always, set to yes, and set to a custom value.
Here's the relevant dialplan on the receiving side:
[from-pstn]
exten => s,1,Wait(5)
exten => s,n,Answer
exten => s,n,MusicOnHold
exten => s,n,Hangup
To trigger the issue this fixes, place a call to the test box, then hang up any time between when you see "Starting simple switch on 'DAHDI/1-1'" and when the call is answered.</pre>
