Hello,
First of all apologies for the basic question.
I'm trying to capture the handshake packets when a SIP handset registers with a PABX & i'm struggling.
I enter the PBX details inc usernames, passwords, etc into the SIP handset. Then i unplug the handset & start the Wireshark then plug it back in.
Once the handset has booted back up I stop the trace & use the display filter to look at the ip address of the PBX to hopefully find the acknowledgement between the PBX & SIP handset but nothing appears. The PBX confirms the handset is registered.
Any idea's?
Thanks. Lee.
