<div dir="ltr">We are currently experiencing an issue on some Cisco 6945 phones which results in devices showing a shared line as on-hold, yet no call is actually present. 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>
<div>3. No amount of line-button/soft-button/hard-button presses seems to clear the line of the phantom. Rebooting the phone will remove the phantom, though.</div><div>4. Calls can be made from the afflicted line</div><div>
5. To date, this has occurred on SIP6945.9-4-1-3 and SCCP6945.9-3-3-2-SR1 firmwares.</div><div><br></div><div>We have found similar bug reports on the Cisco website, but they either apply to other phone series and/or were corrected by the 9.3.X code train.</div>
<div><br></div><div>Has anyone else run into anything similar? Thanks!<br clear="all"><div><br></div>-- <br>Gabriel Jackson<div>Network and Telecom Systems Engineer</div><div>University Technology Services</div><div>(248) 370-4560</div>
