When I first got the 501v I'm sure it was possible to have more than 1 IP Service registered but now only the first registration works even thought the other 5 are there.<br /><br />I also bought a DP450 complete with a handset which I assume is an S45 although there is no model number shown on it.<br /><br />I think the problem may have occurred when I logged the S45 Handset onto the Sinus 501v because I think it did a software update. Anyway, the current software on the 501v is <br /><br />Firmware version: 021890000000 / 043.00<br />EEPROM version: 157<br /><br />I can get to:-<br /><br />Firmware Update<br /> <br /> <br />Data server: <br />User defined firmware file: <br /><br />via the web interface but need to know what to enter in the boxes for 'Data server' and 'User defined firmware file' in order to get the 501v to download a firware version which will restore all 6 registrations.<br /><br />Hopep you can help.<br /><br />PeterUnknownhttps://www.blogger.com/profile/09160505714439122134noreply@blogger.comtag:blogger.com,1999:blog-1660820469479577191.post-88149884678653640872010-09-18T07:32:17.580-07:002010-09-18T07:32:17.580-07:00Just read you post and was hoping to apply the abo...Just read you post and was hoping to apply the above to a locked C470ip, anbody know of wher i could obtain the correct firmware.<br /><br />Thanksinfohttps://www.blogger.com/profile/16121278408556826583noreply@blogger.comtag:blogger.com,1999:blog-1660820469479577191.post-71968345104342988052010-09-13T06:39:44.332-07:002010-09-13T06:39:44.332-07:00I need the same help as Patrik...

I used it to downgrade my T-Com Sinus 501 V (made by Gigaset) from a special provider beta version 22201, to the regular version 214. <br /><br />After downgrade, the webinterface displayed "file corrupt", when i tried to login with "german" or "france" as language setting. but login with "english" worked. Then i have done the update again, with <br />"gigaset.com/chagall" as Server Setting<br />and<br />"gigaset.com/chagall/2/chagall214_02.bin" as userdefined firmware setting.<br /><br />now it also works again in german and france language mode...Lutzhttps://www.blogger.com/profile/16213129257550736599noreply@blogger.com
