[Asterisk-Users] Registration from <xxx> failed for 'xxx'

[Thomas Gallaway]

Hi

Here is my problem. I have 2 phones (Grandstream Budge Tone-100) loosing 
the sip registration
every 4 hours. I can not find out why.

It seems like the registration fails, then a few minutes after registers 
sucessfull.

Mar 19 14:06:14 NOTICE[147466]: Registration from 
'<sip:114 at 192.168.1.3;user=phone>' failed for '192.168.1.114'
-- Executing NoOp("SIP/114-5d35", "") in new stack
-- Registered SIP '114' at 192.168.1.114 port 5060 expires 180

sip show peers show's me this:
116/116          192.168.1.116   (D)  255.255.255.255  5060     Unmonitored

Thanks for any input on this.
