asterisk users - Nov 2009 - Difference between 'core show channels' and 'sip show channels' ??

vps*CLI> iax2 show channels
Channel               Peer             Username    ID (Lo/Rem)  Seq
(Tx/Rx)  Lag      Jitter  JitBuf  Format
0 active IAX channels
vps*CLI> core show channels
Channel              Location             State
Application(Data)             
0 active channels
0 active calls
vps*CLI> sip show channels
Peer             User/ANR    Call ID      Seq (Tx/Rx)  Format
Hold     Last Message   
ip_peer    (None)      58139462bde  00101/20006  0x0 (nothing)    No
Rx: REGISTER              
1 active SIP channel


Core show channels shows 0 active channels.
Sip show channels shows 1 active channel.

I find it odd to have 1 active channels... Mostly there are 2, 4, 6
channels as a SIP-conversation consists of 2 channels :
user1 ---- asterisk ---- user2


And then some minutes further :

vps*CLI> core show channels
Channel              Location             State
Application(Data)             
0 active channels
0 active calls
vps*CLI> sip show channels
Peer             User/ANR    Call ID      Seq (Tx/Rx)  Format
Hold     Last Message   
ip_peer     0a27b9c7d   37df36b96ba  04717/00000  0x0 (nothing)
No                                 
ip_peer     (None)      24ddc4be2b2  00101/00119  0x0 (nothing)    No
Rx: REGISTER              
2 active SIP channels


Can someone enlighten this ?

Jonas.

You caught an endpoint registering - that is a channel while the 
conversation to register is occurring.

One is a register again, not sure about the other.
