Assuming that you have context=incoming on your fxo channels in zapata.conf,
then the above context=incoming should be okay for starters.
In your sip.conf file, the type=friend should not have host=64.123.157.103,
as 'friend' implies the phone is registering with asterisk and therefore
asterisk knows the IP from that registration.
In sip.conf, your start out with context=local-access and then define
extension 20 within "that" context. But, in extensions.conf you
don't
have any definitions for [local-access]. It kind of looks like you
should change context=local-access to context=extensions in your
extensions.conf file.
If you can't make the phone operate without the host= statement, then
debug why the phone isn't registering correctly.
