[OpenSIPS-Users] Cannot call due to 408 error

Hi all.

I am a newbie to OpenSIPS. I succeeded in installing it thanks to the
webinar 'OpenSIPS kickstart' in opensips.org. I have also installed the
OpenSIPS control panel and MySQL based authentication successfully. I was
able to register several SIP soft/hard phones and make calls successfully
as well (initially).
But after few minutes I cannot make calls between the phones. It returns a
408 error saying that the user cannot be found in time. The phones are
still registered but it seems that OpenSIPS has forgotten the location of
the phones. I checked in the MySQL database and it contains the URI s with
the IP addresses of each phone in the 'location' table.

But once a call attempt from one phone fails, immediately afterwards
(within 1 minute or so) I can call that phone (the phone which returned the
408 error) from another phone successfully.

Does OpenSIPS throw away the location info of a user after some time?
Please help

Thanks in Advance
