T28-P firmware 2.71 fail communication - pixfw - 10-01-2013 06:28 AM

I am using T-28 phones with the new firmware (, with vlan1 for data and vlan2 for voice.
The ping response is very high and intermittent, I can't make calls.
Please give me any tips.

(With the old firmare version works fine.)

Hi Pixfw,
So now the problem is can't make or receive the call on this T28 phone?

Could you provide PCAP trace, syslog(level 6) and config.bin file to us, so we can analyze?
Before you export the syslog, please set log level as 6, and reboot the phone, then click Start,and reproduce the issue, then click Stop,and export the trace, syslog, config,bin to us.
(About where to export these files, please refer to attached screenshot.)
These three files are very important for us, hope you can kindly understand.

BTW, could you also provide these three files in old firmware which works fine for us reference?
