[Asterisk-Users] erroneous errors - registration fails for grandstream phones

[Greg - Cirelle Enterprises]

Has anybody seen this behaviour?

sip conf is stored in mysql database in 2 tables
ast_config for static (general) key/values

sip_buddies for sip extension detail.

database on the same machine as asterisk


Grandstream phones (I happen to have 2) register with asterisk
via sip with accounts and passwords successfully for a variable
period of time. Then after a while, i get errors which appear to
be erroneous since the phones/extensions apparently are working.

example of 1 phone, but it happens with both:

*** from asterisk CLI>
     -- SIP Seeding '40852' at 40852 at 192.168.20.25:5060 for 2400

     -- Saved useragent "Grandstream BT100 1.0.5.20" for peer 40852
     -- SIP Seeding '40852' at 40852 at 192.168.20.25:5060 for 2400

The date obviously changes
