<div dir="ltr">Make sure all the phones with the shared line are all registered to the same CUCM node. The shared line inter-node communication doesn't scale great. 10 phones is a lot for a shared line. Can you possibly move away from the shared lines to a broadcast hunt group instead?</div>

We can't reproduce this issue on demand, but we have noticed the following is true when it occurs:<div>
<br></div><div>1. The shared line often has high call volume and is shared by as many as 10 devices.</div><div>2. The phantom hold will often only affect a single device, resulting in the phone being out of sync with its peers.</div>
