In the latest version, the feature code “In-Call Asterisk Disconnect Code” was removed.
From the support team:
“In-Call Asterisk Disconnect Code” we removed that. It doesn’t do anything. The decision was to remove the feature code completely
After a call transfert with “*2”, If you get the voice mailbox message instead, we dial the “In-Call Asterisk Disconnect Code” (’’**’’) to get back to the original caller and explain the person is away.
