Asterisk with T21P E2 provisioned - call problem

[mhterres]

Hi.

I upgraded the firmware as you told me.

Using T21P_E2
Firmware Version 52.80.0.95
Hardware Version 52.0.0.0.0.0.0

But problem persists:

[Mar 1 14:09:52] WARNING[2442][C-0000022b] chan_sip.c: username mismatch, have <3258>, digest has <IP Phone>
[Mar 1 14:09:52] NOTICE[2442][C-0000022b] chan_sip.c: Failed to authenticate device "3258" <sip:3258@192.168.0.8:5060>;tag=3352111893

Just after factory reset, provisioning works and I can call, but after telephone is rebooted the problem starts again.

Another info: I'm using the same provisioning with T19P_E2 with 53.80.0.70 and I can't reproduce the problem.

Regards,
