If you record route, SER stays in the signalling path. Any proxy in the path between two UAs that record route will stay in the path. g-)

Several sources have told me that, once a call has been established, SER does not stay in the message path between the caller and callee. However, after examining some packet traces in Ethereal, I'm a little confused.
I have the following setup: Caller -> SER -> Asterisk -> VoIP Provider -> Callee When I start tcpdump on Asterisk and place a call to the PSTN, the only devices that Asterisk is sending data to and receiving data from are SER and the VoIP provider.
Doesn't this mean that SER does in fact stay in the SIP message path for the duration of a call?
Thanks for explaining this, -- Nick e: nick.hoffman@altcall.com p: +61 7 5591 3588 f: +61 7 5591 6588
