type=peer,user не соответствие мануалу

Из мана (sip.conf.sample):

The SIP channel has two types of devices, the friend and the peer.

The type=friend is a device type that accepts both incoming and outbound calls,where Asterisk match on the From: username on incoming calls. (A synonym for friend is "user"). This is a type you use for your local SIP phones.

The type=peer also handles both incoming and outbound calls. On inbound calls, Asterisk only matches on IP/port, not on names. This is mostly used for SIP trunks.

Values for "type" keywords in sip.conf and iax.conf type = value

peer: A SIP entity to which Asterisk sends calls (a SIP provider for example). If you want a user (extension) to have multiple phones, define an extension that calls two SIP peers. The peer authenticates at registration.

user: A SIP entity which places calls through Asterisk (A phone which can place calls only). Users authenticate to reach services with their context.

friend: An entity which is both a user and a peer. This make sense for most esk handsets and other devices. Asterisk will create two objects, one peer and one user, with the same name.

Где правда? По первой версии user (friend) тот кто авторизуется при вызове, а peer нет, по второй user тот кто только звонит, когда по первой версии он и принимать может..
