asterisk users - Mar 2006 - Ok... what is 'sip show peers' really used for?

I'd love to understand what the function of the peer list returned by
'sip show peers' is for, especially when Realtime is used.

If I start Asterisk with realtime enabled, a 'sip show peers' yields
none. As each peer (phone) registers, or a call is made to the peer, Asterisk
adds them to the list returned by 'sip show peers'. Correct?

Apparently Asterisk doesn't refer to thie list however, when deciding where
a peer is located. It uses astdb instead (I have rtcachefriends=yes). I cleared
the fullcontact field in the database, and placed a call. The only place that
Asterisk could get the peer's IP address from was astdb, as the peer
wasn't in 'sip show peers' as I purposefully cleared the fullcontact
field for all peers in the database.

So... what's the point of this? Is it used for anything? It looks like it
uses it for voicemail, but that's it. Ie if the peer isn't in 'sip
show peers' then voicemail does not get delivered, EVEN if it's in
astdb.

Also, if all my phones are defined as friends, why does a 'sip show
friends' return a smaller list than 'sip show peers'??? If the
phones are all defined as friends, which are both peer and user, then a 'sip
show friends' should return all the phones, but it does not.

No wonder I'm confused.

Well, we use sip show peers when qualify=yes so we can monitor when a 
phone goes offline and so we can just look there for the ip address of 
phones.

I use it to order pizza. Just kidding, but among others it tells you
what IP address Asterisk knows for a peer, as well as the qualify
status.

NO. We don't use astDB during operations, only at reload of  
registered static peers. I said it before, didn't I?

sip show peers shows the in-memory peers, static peers or cached  
realtime peers. Those get
MWI notification and qualify= checks. This is documented in many places.

"Sip show friends" should generate an error message, since that  
command does not exist.

How does it do that? A 'sip show peers' doesn't show an IP address
for the peer. Does it store it internally, and not show you when do you a
'sip show peers', or does it pull the IP address from astdb?

I don't know. Did you? A reload of registered, static peers.... how?

I have seen different. I quite clearly performed a test where sipusers and
sippeers pointed to MySQL. Astdb was populated, and sip peers was not yet. MWI
did not work. Upon new voicemail deposit, mwi did not work. I reverted back to
sip.conf, astdb was still populated, and sip peers was then immediately
populated (as realtime was disabled). Upon new voicemail deposit, mwi did work.

My bad. I meant 'sip show users'.... same question remains. Why
doesn't 'sip show users' show the same output as 'sip show
peers' then?

Hang on a minute.... If the astdb file is not used when realtime is in effect,
how the heck can I make calls to phones that aren't in the 'sip show
peers' list? (hint: I CAN make calls to phones not in the peer list, but in
astdb)
