<p class="MsoNormal">We did try to ping from the 4500 (default gw) while it was happening, without any success. I wasn't in the 'driver's seat' but pretty sure the network ops guy just used ping without any other options - i'm a wee bit unclear on which source
 interface IOS picks at that point but i'm assuming it would choose the SVI for the vlan since its directly connected. I didn't think to ask him to use extended commands and specify the source interface to be sure though.<o:p></o:p></p>

<p class="MsoNormal">If I can't duplicate this in the lab this afternoon with a 4500 I will probably end up making a new voice vlan and subnet w/o hsrp so I can move them over a few at a time instead of all at once. Relatively straight forward, but i'll have
 to reconfigure SRST, and it won't explain why we even had the issue in the first place.<o:p></o:p></p>
