<BODY>That makes sense - I have quite a few SCCP controlled conference bridges still using the 4.1 keyword with CUCM 6.1 that we have not got around to changing yet. These are working with no problems In a perfect world you would have all of your routers/gateways on the latest IOS and co-ordinate changing the config with your upgrade. Unfortunately this is not always practical. <BR><BR>>>> Pavan K <pav.ccie@gmail.com> 6/9/2010 10:35 PM >>><BR>If i am not mistaken,
<DIV><BR></DIV>
<DIV>the (ccm) version keyword in IOS is used by the router to determine the Skinny version used to register with CCM.</DIV>
<DIV>As such a CCM v7.1 can very well understand its own skinny version and all previous skinny versions.</DIV>
<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>Basically with the sccp version mismatching you can expect one of three things to happen.</DIV>
<DIV>1. No dspfarm media resources will register.</DIV>
<DIV>2. They will register, but calls will fail.</DIV>
<DIV>3. They will register, some calls will work, others will fail in strange and unpredictable ways. </DIV>
<DIV><BR></DIV>
<DIV>This one is guaranteed to happen every time.</DIV>
<DIV>4. TAC will yell at you to upgrade your IOS.</DIV>
