I am in the process of testing a new Yealink US/China firmware for the T38. (these features are already in the T2x series) The changes are: 1) Add the feature Multicast Paging. 2) Add the searching feature on caller side of xml phonebook 3) Add the xml browser feature. This is great news for those large installs where a Ring Group to many phones is not suitable for Paging. So far so good. I am just having trouble figuring out how to create the template for receiving Multicast pages.
