Fortinet 60D 3/4G failover

Hey There,I found some thread on setting up a Fortinet 60C with 3G redundancy. I have pretty much gotten to the same point as previous threads.My configuraton just sitting on 'connecting'.Just a brief run down on my setup.Fortinet 60DHuawei E8278 Dongle - I had to create the modem manually in the firewall as it was using an alternative one.

config system modem

set status enable

set auto-dial enable

set connect-timeout 30

set phone1 "*99#"

set extra-init1 "at+cgdcont=1,\"ip\",\"wap.telecom.co.nz\""

end

I feel that it may be the port that is wrong like mentioned in other threads, but i am not sure on how to get it changed or to which one. Could you shed some light on this for me?In advance, thanks for your help.Buddy.
