<p class=MsoNormal>I think it's a bug in chan_dahdi.c, I have not tested but
checking what application CHANISAVAIL does, the code path seems like
unexpected, when ast_request() is called I set mfcr2call=1 to reserve the
channel, but in ast_hangup() I do not set mfcr2call=0 because the usual code
path is ast_request() -> ast_call() -> ast_hangup() and at that point
openr2 callbacks will report call end and I will set mfcr2call=0, but when just
checking if the channel is avail, the call is never initiated and the
mfcr2call=1 flag keeps set after ast_hangup().<o:p></o:p></p>

<p class=MsoNormal>This bug will be present in all patches for Asterisk and

and create a new patch for 1.4 probably the weekend, or sooner if I can. <o:p></o:p></p>

<p class=MsoNormal>Hi,<br>
We are having problems with chanisavail.<br>
<br>
Everytime we use chanisavail to check for channel availability, when using R2,
the channel gets locked.<br>
We tested with 1.4.22, 1.4.24 and 1.4.26, using OpenR2 release 209.<br>
<br>
Chanisavail works fine if the E1 is ISDN<br>
But chanisavail gives error and locks the channel if we configure the E1 as R2.
Next run, it locks the second available channel and so, until we get all 30
channels locked. Then we have to restart.<br>
<br>
<br>
All other applications and the asterisk itself is working fine with R2<br>
<br>
<br>
<br>
Can anyone please test this and confirm this problem?<br>
<br>
<br>
<br>
Here is a simple dialplan for testing:<br>
<br>
<br>
exten => 123,1,noop( ---- TESTE CHANISVAIL ---- )<br>
exten => 123,n,CHANISAVAIL(dahdi/g1)<br>
exten => 123,n,NOOP(CHAN=${AVAILCHAN})<br>
exten => 123,n,SET(CHAN=${CUT(AVAILCHAN||1)})<br>
exten => 123,n,DIAL(${CHAN}/1234)<br>
exten => 123,n,NOOP( STATUS = ${DIALSTATUS})<br>
<br>
<br>
<br>
Thanks in advance,<br>
<br>
