I'm sorry we can't do more troubleshooting without syslog(level 6) and PCAP files.

After set the IPV6 configuration, the phone will reboot. After reboot, please go to settings->configuration to enable syslog level as 6 and start PCAP feature, you can push the phone to register.

Then you can reproduce the issue and export all files to me.

Thanks for your help.


Hi Kevin,

The syslog files were included in the zip file I emailed you - inside the two different folders. Did you not see these or was there something wrong with them?

The phone only seems to generate blank pcap files when following your instructions below. Is this a known issue with the T58?


Hi Reuben

The PCAP file is empty, the syslog file don't have SIP processing information. So it can't help us to do more troubleshooting.

I test in my side, T58V don't have any issue with capturing. So please set syslog level as 6, and start PCAP feature.

After that ,you can register again. It should work and export all files to me.
If you can connect your PC to PC port and enable 'span to PC' feature, you can capture PCAP on your PC.

Can you tell me how many phones will you need after testing.
