[asterisk-users] seed vs registration?

[Benjamin Jacob]

Hello ppl,
The scenario :
I restart asterisk, sip show peers shows nothing.
I make a call from 7013 to 7011.
I get the following o/p :
SIP Seeding peer from astdb: '7013' at 7013 at 192.168.10.53 for 3600

SIP Seeding peer from astdb: '7011' at 7011 at 192.168.10.45 for 240

And then the call goes thru.

So, does 'Seeding', means * registers both users??

But a subsequent REGISTER msg shows :
 Registered SIP '7011' at 192.168.10.53 port 10016 expires 240

n so on.
So how does REGISTER differ from Seeding?

Also, what should be the defined behaviour if the caller and/or callee 
is/are not registered when they attempt a call(INVITE)?

Thanks in advance.

cheerz
