<br><tt><font size=2>I haven't tested this, but my initial thought would
be to create a special context or extension that the secretary could route
through when doing the call transfer. The Dial application could be called
with the 'g' option to continue the dialplan at the next priority when
the call hangs up. Something like a normal call transfer would just dial
the number as normal, but for the special transfer, you could prepend the
dialed number with a #.</font></tt>
<br>
<br><tt><font size=2>For example (using a local US dialstring, change to

<br>
<br><tt><font size=2>; This is a normal external call.</font></tt>
<br><tt><font size=2>exten => _NXXNXXX,1,Dial(SIP/your_external_trunk/${EXTEN})</font></tt>
<br><tt><font size=2> same => n,Hangup()</font></tt>
<br>
<br><tt><font size=2>; This is a call that should be transfered back to
the secretary's extension when external call is finished</font></tt>
<br><tt><font size=2>exten => _#NXXNXXX,1,NoOp(Special Dial for Boss/Secretary
Transfer)</font></tt>
<br><tt><font size=2> same => n,Dial(SIP/your_external_trunk/${EXTEN:1},,g)</font></tt>
<br><tt><font size=2>; First call has ended, now we go back to the secretary)</font></tt>
<br><tt><font size=2> same => n,Dial(SIP/1234)</font></tt>
<br><tt><font size=2> same => n,Hangup()</font></tt>
<br>
<br><tt><font size=2>That's at least where I would start with my testing
