e61i error using VOIP

[henry]

Hi

I am regularly got this error when try to connect lowratevoip.com using wifi by connecting through Internet Telephony.
App. closed:
IPWServer
E32USER-CBase 47

App. closed:
Internet tel.
ViewSrv 11

After I got that error msg, my phone will slow responding.
The only solution to make it normal is by turn off/on back the phone.
Then I can connect normally

I almost never encounter this problem with my older e61.
My FW is 1.0633.22.05.
Nokia should fix this problem ASAP.
When new FW coming?

thanks

Henry
