Auto voice VLAN port not staying in "Tagged Membership" after aging period.

I have a 3Com Baseline Switch 2916-SFP Plus (basically an HP V1910-16G JE005A) and have setup the auto voice VLAN (Device / Qos / VoIP Traffic) feature. I've edited the OUI and added my phone's MAC prefix.

 

This seems to work well. The first time the phone boots the port it is connected to shows up in "Tagged Membership". However, when the "VoiceVLAN Aging Time" ends the port no longer is tagged even though the phone has been in use during that time.

 

Is this normal behavior? I'm running the latest software version 01.00.10.

Re: Auto voice VLAN port not staying in "Tagged Membership" after aging period.

The manual states:

Voice VLAN Aging Time — Defines the amount of time after the last IP phone's OUI is aged out for a specific port. The Voice VLAN aging time starts after the MAC Address is aged out from the Dynamic MAC Address table. The port will age out after the bridge and voice aging times. The default bridge aging time is 300 seconds. The default voice aging time is 1 day.

 

So, why is the phone's MAC being aged?
