[asterisk-users] Problem with AASTRA phone of NO SERVICE

[antselva at tiscali.it]

Hi,

I have 2 phones AASTRA 57i with Asterisk 1.6.
When the internet 
connection for some reason fall down the 2 phones go to "NO SERVICE", 
searching on internet i found that this is due to DNS service.
Has 
someone solve this problem? or suggestions?

Thanks in advance

Antonio
