[Asterisk-Users] Shutting down Asterisk when not in RTP Stream

[Douglas Garstang]

I'm very confused about something.

I have two phones that have reinvited and have an RTP session open. I confirmed this by running ngrep on the Asterisk box. Asterisk still shows the calls on the console.

*CLI> sip show channels
Peer             User/ANR    Call ID      Seq (Tx/Rx)  Form  Hold     Last Message   
192.168.10.125   a00090201   45dfabad1bd  00103/00000  ulaw  No       Tx: ACK        
192.168.10.4     a00090101   ca3279d8-3e  00102/00001  ulaw  No       Tx: ACK        

When I shut asterisk down, the call terminates. I don't understand that. If Asterisk isn't in the RTP path, how can shutting it down terminate an active call?

Don't know if it's relevant, but the 192.168.10.4 is an OpenSER box. 

Thanks.
Doug.
