Title: Message
Are the SIP messages running on the registered SIP port? If not, select a SIP packet from your capture, right-click on it and choose "Decode As", then choose the port from the pull-down menu, and choose SIP for it.
 
Is the SIP protocol version "SIP/2.0"? If not, then you need the new SIP dissector as from yesterday. It contains a SIP preference that allows to disable strict "SIP/2.0" version matching. If you can't build Ethereal from the sources or you can't wait for the next official Ethereal release, feel free to send me the capture and I'll reply with the decoded output.

Hello,

 

I am using the latest version of ethereal 0.10.0 and I am trying to capture SIP messages from an IP phone. I have a Cisco ATA which is connected to a LAN thru a hub to which my computer is also connected. I start ethereal and switch on the ATA. But when I stop the packet capture after some time, I do not see a single SIP message. I do get a dial tone in the ATA though. Is there anything that I am missing here?

 

Thanks

Santosh
