Hi,
Go to the web page of the phone. Each line under the SPA has a Dial-Plan option. You just need to paste the next code in order to do the PLAR (HotLine).
(P1<:extesion> | (9,8<:1408>[2-9]xxxxxx | 9,8,1[2-9]xxxxxxxxx | 9,8,011xx. | 9,8,xx.|[1-8]xx)
PX=Pause for X second.
extension= where you want to auto dial.
In my case
(P1<:2002> | (9,8<:1408>[2-9]xxxxxx | 9,8,1[2-9]xxxxxxxxx | 9,8,011xx. | 9,8,xx.|[1-8]xx)
the phone automatically call to extension 2002
