[Asterisk-Users] BT102 phones giving strange errors

[Carlos Chavez]

     I have an * server running 1.0.9 on a FC3 machine.  I connect around 44
BT102 phones to it and 6 Sipura 2000 units.  Everything is working great but
lately I have seen the following error:

Aug  4 13:33:24 WARNING[31907]: chan_sip.c:4826 check_auth: Stale nonce
received from '<sip:4000 at 148.235.174.85>'
Aug  4 13:33:24 WARNING[31907]: chan_sip.c:4826 check_auth: Stale nonce
received from '<sip:4000 at 148.235.174.85>'

     Only two or three phones send this error.  The phones seem to send and
receive calls without any problem so I do not know if I should be concerned by
this or not.  The message appears quite often, about once every 5 minutes. 
The phones have the proper authentication information so I do not know what
this message refers to.
