A type=friend is simply both a type=user and type=peer using the same
set of config directives. While a type=friend makes things almost
trivial to get calls working in both directions, it will limit the
flexibility of your config and even hinder some of the more advanced
uses of Asterisk.

For example: Say you want to use the same 'user' across many
different Asterisk boxes, which of course will have different IP
addresses. In this situation, you cannot have a host keyword in your
Asterisk config stanza for the type=user, but the type=peer requires
some host keyword. Thus, if you use a type=friend you will limit the
use of that one username to whatever IP address is contained in the
host keyword.

You only need to register to Asterisk if you have a dynamic IP
address or you need to blow thru a firewall/NAT device. To register
you need to have a type=peer with a host=dynamic. Since in your
type=friend config directive you had host=some.ip.address, while this
may be this is fine to for the type=user, this same value also gets
used for the type=peer, which makes it so you cannot register since
the IP address is hard coded.

So, either you do not need to register and things will Just Work(tm)
or you will need to use separate type=user and type=peer config
directives.



So, why can't you just do:


[someuser]
type=friend
host=dynamic
context=internal
secret=somesecret

In other words, you can have your user registered to the server AND be
using a type=friend definition. This is exactly how I have some test
equipment set up and it works perfectly well.






Sure, but then you are not restricting to any specific IP address to authenticate users and you will request the internal context on the far end when sending them calls.
