<div dir="ltr">Hi All,<div><br></div><div style>I am using mod_fifo for park/unpark like application using diaplan below, everything works great, I am able to park/unpark calls, transfer back to the extension that parked the call on timeout and remove FS from signaling path after transfer using uuid_simplify.</div>
<div style>What I wasn&#39;t able to accomplish is to remove FS from signaling path after unparking the call, tried both uuid_simplify and setting sip_auto_simplify variable without luck. Any idea if this is possible?</div>
