Unless I'm missing something too, the inability to lock an available
channel appears to invalidate any potential use of ChanIsAvail.<br>
<br>
It would be nice to be able to tell ChanIsAvail to lock an available channel until Dial is used or the dialplan logic ends.<br><br><div><span class="gmail_quote">On 9/13/05, <b class="gmail_sendername">hugolivude</b> <

ChanIsAvail in a dial plan to determine which line to use because a
line that tests as AVAILABLE could get snatched by another user before
it can get used. Am I right or have I missed something?<br>
<br>
Thanks,<br>
