&lt;hr /&gt;
&lt;div&gt;== Applies To ==&lt;br /&gt;
This information applies to:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;!-- * All V8 capable innovaphone devices --&amp;gt;&lt;br /&gt;
* All PBX devices&lt;br /&gt;
* All DECT devices&lt;br /&gt;
&lt;br /&gt;
&amp;lt;!-- ===Problem Details=== --&amp;gt;&lt;br /&gt;
== Configuration Changes ==&lt;br /&gt;
&lt;br /&gt;
=== PBX Objects ===&lt;br /&gt;
Existing &#039;&#039;&#039;Broadcast Conference&#039;&#039;&#039; objects must be changed with the update to V9 Final &#039;&#039;&#039;till V9 Hotfix 6&#039;&#039;&#039; if an innovaphone [[Reference:Administration/Gateway/Interfaces#Conferencing_interface_.28CONF.29|Conferencing Interface (CONF)]] is used. Add the &#039;Conference Id Prefix&#039; &#039;*3&#039; in all BC Conference objects, see also &lt;br /&gt;
[[Reference:Administration/Gateway/Interfaces#Conferencing_interface_.28CONF.29|Conferencing Interface]]. With V9 Hotfix 7 and later a predefined id prefix and suffix are used and nothing must be changed if the innovaphone Conferencing Interface is used. With &#039;&#039;&#039;V9 Hofix 7 and later&#039;&#039;&#039; the &#039;&#039;&#039;3rd Party Conferencing Unit&#039;&#039;&#039; option in the Broadcast Conference objects must be ticked again if a third party conference unit is used.&lt;br /&gt;
&lt;br /&gt;
==Known Problems==&lt;br /&gt;
&lt;br /&gt;
=== H.323 pickup execute encoding changed ===&lt;br /&gt;
If you use V8 DECT devices, the internal DECT feature code &#039;Pickup&#039; is not correct working with a V9 PBX. The call is not connected, but the device is called back by the PBX.&lt;br /&gt;
&lt;br /&gt;
Workaround: Update the DECT device to V9, use the PBX object DTMF features or use the call pickup with call back.&lt;br /&gt;
&lt;br /&gt;
=== innovaphone voicemail===&lt;br /&gt;
Mailboxes with vowel mutation (umlaute/umlauts), like ü,ö,ä (for example Müller, more precisely mailboxes for users with non-ascii characters in the name) did  work anymore when upgrading from pre-V9 versions to early V9 development versions.  This has been fixed from build 90423.  Pre-V9&lt;br /&gt;
&lt;br /&gt;
=== licenses with certain characters in license comment===&lt;br /&gt;
See [[Support:V8_to_V9_update_with_license_comments_with_certain-characters|V8 to V9 update with license comments with certain-characters]].&lt;br /&gt;
&lt;br /&gt;
=== Config Templates chained ===&lt;br /&gt;
Since there were changes on mechanism from v8 to v9, if there is a complex scenario with chained templates (3 or more) some configurations (ie. function keys) of &amp;quot;upper&amp;quot; templates are lost so it&#039;s needed to rework manually this &amp;quot;chains&amp;quot; on v9 setup setting the full &amp;quot;tree&amp;quot; of chained templates (up to 4) plus the checkmark of store-phone config in each template. &lt;br /&gt;
&lt;br /&gt;
=== Incompatibilities between certain Firmware Versions in V7, V8 and V9 ===&lt;br /&gt;
There are [[Support:Firmware_v9hotfix3_/_v8hotfix19_/_v7hotfix31_should_not_be_mixed_with_earlier_versions | incompatibilities between newer and older V7, V8 and V9 firmware builds]].  As a result, you should not mix these versions.  However, contemporary builds of all these version do not hae the problem.  It is recommended thus to upgrade all V7 and/or V8 builds to the latest version &#039;&#039;before&#039;&#039; starting the migrateion.&lt;br /&gt;
