Important Differences between SIP 3.2.5 or previous to UCS 3.3.x or 4.0.0:
NOTE:
Prior to UC Software the Phone always needed to load a sip.cfg and a phone1.cfg matching the SIP Release that was currently installed on the Phone via the 000000000000.cfg or <mac>.cfg.
Example:
Parameters like the Corporate Directory for example need to be activated in addition to a Productivity Suite license depending on the Phone Model and/or Software Version.
The activation in UCS 3.3.0 or newer works via:
< feature feature.corporateDirectory.enabled="1/>
The activation in SIP 3.2.x or previous works via:
<feature feature.19.name="corporate-directory" feature.19.enabled="1"/>
Above is a common mistake to be made when configuring phones.
Another Example is KEY Programming
UCS 3.3.x and later:
<button><key key.SPIP335.34.function.prim="Null"/></button>
SIP 3.2.5 or earlier:
<button><key key.IP_330.34.function.prim="Null"/></button>
