I have an Asterisk server (Trixbox 188.8.131.52) running SIP with SPA 509G handsets with fw ver 7.4.7. I am trying to get call park working with a softkey and just cannot figure it out. There is no park button when I am connected to a call, even though I have it set to display in my connected key list in the web gui. It would be huge help to have a one touch park button because right now users have to bxfer>70>dial everytime to park which is a feature we use constantly. Any ideas would be greatly appreciated.
