Hello, Does anybody know when I can find firmware for Swissvoice Vizufon (CIP-5500)? Google isn't sayng anything... I want to update firmware because when I call somebody, Asterisk says: WARNING[22728]: chan_sip.c:4826 check_auth: Stale nonce received from '<sip:xx@xxx.xxx.xxx.xx>' sip.conf is: [xx] type=friend host=dynamic qualify=yes callerid=asd fromuser=xx username=xx secret=pass context=somecontext In phone I have user name and auth. id set to xx and password to pass. -- Best regards, Bartosz Piec
