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@192.168.10.53 for 3600 SIP Seeding peer from astdb: '7011' at 7011@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 - Ben
