[8.940013][QUESTION]How to track SIP setup

Hi,
After the up2date installation one of my VoIP phones no longer works eg can't register.

I have looked through the various logs to track the packets or error messages, but I have not found any.

My VoIP phones are on a seperate network, so the IP address would be very obvious in any of the logs.

Any ideas where I might look?

Ian

Interesting thing to note is the VoIP usage now peaks higher in the network utilsation graphs., used to be around 84kb now around 110kb.
