<p style="margin: 0 0 1em 0; color: black;">Hi,</p>
<p style="margin: 0 0 1em 0; color: black;">Recently we had a similar issue
with limit and as you know it doesn't work across dialplan so we started
using hash where we increment a counter for the caller and callee and once
they hang up we decrement it and in transfer situation we call the attended
transfer extension in features dialplan where we take the input of the
extension to be transferred to then we call execute extension to parse the
features dialplan again and then we increment the counter for the callee
where call is to be transferred.</p>
<p style="margin: 0 0 1em 0; color: black;">This way the counter for all
parties is incremented properly and we use api hangup hook to decrement the
hash value in the bridge statement so when that party hangs up the counter
is automatically decremented.</p>

<p class="MsoNormal" style="">Hi All,</p>
<p class="MsoNormal" style=""> </p>
<p class="MsoNormal" style="">In our environment we restrict the number of
current channels (using limit) per extension, however using attended
transfer allows extensions to exceed the limit since leg a ends once the
transfer completes which resets the limit
to 0.</p>
<p class="MsoNormal" style=""> </p>
<p class="MsoNormal" style="">I believe the solution is to apply the limit
on leg b, however leg b is initiated via a bridge (with-in our outbound LUA
script).</p>
<p class="MsoNormal" style=""> </p>
<p class="MsoNormal" style="">How can we apply the limit to leg b, or is
there a better solution?</p>
