[Asterisk-Users] Grandstream Early Dial

[Aaron Martin]

I have upgraded my grandstream phone from firmware 1.0.3.78 to 10.0.4.30 and now I am having problems with early dial.  On the older firmware earlydial worked fine with my asterisk server, but now as soon as I have dialed the number I get a congested tone, and the number 4 flashes up on the LCD screen.

Has anyone had this problem, and if so, how do I fix it?
