Quite often I get the following: 01:59:46 Register attempt for proxy sip:30149331*201@sip.voipfone.net failed 01:59:46 488 Try Again In One Minute Although outgoing works, incoming calls obviously dont as its lost registration. If I shut Express Talk down and start it again all is well and incoming calls work again. Sometimes Talk can be fine for hours before it does this, other times an hour. Anyone had this ?
