<div><br></div><div>That being said, an incompatible bug fix / enhancement is what causes a new skinny version to being added.</div><div>so its generally recommended to be on the latest SK version. </div><div><br></div><div>

<span style="color:black">What happens if a router is left running with keyword version 4.1 but you upgrade Callmanager to 7.1(3b)SU2 ? I can’t seem to tell a problem, it looks like conf and transcoder stay registered, but surely there must be a reason the keyword got updated, etc.</span></div>
