I have ip phone SPA502G and SPA504G

I have a IP GSM gateway for incoming and outgoing GSM call

I configured the uc-560(192.168.20.1) and the GSM gateway(192.168.20.3) and everything gave worked fine during 1 month

Are you able to ping the your ITSP? You can also remove your SIP trunk and set it up again through CCA.  Click on the Telephony\Trunks\SIP Trunk.  From there just re-enter your ITSP's settings.
