</div><pre style="font-family: monospace,monospace; white-space: pre-wrap;">app_dial: Fix dial status regression.<br><br>ASTERISK_28638 caused a regression by incorrectly aborting<br>early and overwriting the status on certain calls.<br>This was exhibited by certain technologies such as DAHDI,<br>where DAHDI returns NULL for the request if a line is busy.<br>This caused the BUSY condition to be incorrectly treated<br>as CHANUNAVAIL because the DIALSTATUS was getting incorrectly<br>overwritten and call handling was aborted early.<br><br>This is fixed by instead checking if any valid peers have been<br>specified, as opposed to checking the list size of successful<br>requests. This is because the latter could be empty but this<br>does not indicate any kind of problem. This restores the<br>previous working behavior.<br><br>ASTERISK-29989 #close<br><br>Change-Id: I4d4b209b967816b1bc791534593ababa2b99bb88<br>---<br>M apps/app_dial.c<br>1 file changed, 5 insertions(+), 2 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;"><span>diff --git a/apps/app_dial.c b/apps/app_dial.c</span><br><span>index edcce0a..4c4ebeb 100644</span><br><span>--- a/apps/app_dial.c</span><br><span>+++ b/apps/app_dial.c</span><br><span>@@ -2703,7 +2703,8 @@</span><br><span> </span><br><span> if (!tc) {</span><br><span> /* If we can't, just go on to the next call */</span><br><span style="color: hsl(0, 100%, 40%);">- ast_log(LOG_WARNING, "Unable to create channel of type '%s' (cause %d - %s)\n",</span><br><span style="color: hsl(120, 100%, 40%);">+ /* Failure doesn't necessarily mean user error.
