asterisk users - Aug 2009 - sip.conf parameter and sip msg between server <-> client

Hello

I have few questions :
- what's the difference between a subscribe request et a register request ?
- in asterisk 1.6 allowguest=yes or no param does it work ? if yes, please
someone could explain how doest it work because I think i'm a little bit
confuse.

- if I configure a sip terminal in sip.conf like this
[john]
type=friend
username=JOHN
secret=mypassword
host=dynamic
context=default

these affirmations are right or wrong :
a) 'john' and 'mypassword' are variables which are used when I
want to
"connect" my softphone or phone to Asterisk server (register request)
AND
when I initiate a call (invite request)?
b) 'dynamic' mean that [john] will be automatically registred to
Asterisk
server and 'qualify=yes' parameter may not be necessary ?
c) in your softphone setting (here i use xlite), parameter 'username'
must
be the same as parameter 'username' in sip.conf ?
d) in you softphone setting (here i use xlite), parameter 'Authorization
username' must be the same as parameter [john] in sip.conf ?
e) instead of using 'dynamic' for parameter 'host', if I use @IP
or a
hostname or FQDN, parameter qualify must set to' yes' or to
'2000' in order
to Asterisk server can know when [john] is reachable ?

regards

H.

Hello,

well let me explain one part of your question, the host parameter. if
you want to restrict the access to one ip you can say it here.
"host=192.168.2.13" means, that you can only use this account from
192.168.0.13, eg. for security reasons. i recommend so set it to
"dynamic" at the moment and if it works you can change if you wish.

aot of information about the sip.conf you can find here:

A subscription in the SIP protocol is saying "Hey, I'd like to be
notified when something happens."  This is most often used when a phone
wants to subscribe to the state of another extension, or to the status
of a voicemail box.

A registration is where one SIP device tells another "Hey, I'm over
here.  If you get any calls for me, send them to me at this IP address
and port."
