configured spa400 as per the instructions given in this thread.
On asterisk side I configure sip.conf with
[general]
register=spa400@10.0.0.114 /spa
and from GUI of Freepbx i created a trunk with name spa400 and the following settings;
canreinvite=no
context=from-trunk
dtmfmode=rfc2833
host=10.0.0.114
insecure=very
type=friend
user=spa400
then from GUI, outbound routes option i created a route to dial out using the trunk spa400------Till this point every thing is working i can dialout using spa400.
I dont know what to do for incoming calls in GUI of Freepbx. I already tried to add the following in extensions.conf
