I have this router with up to date firmware 083. My ISP is Vodafone Es (Spain) as that's where I am living. Vodafone Es allow access to this router only with vodafone, but not with admin or support privileges. I would like to be able to enter with admin privileges.

I have followed the wiki instructions to get admin privileges and they work fine. If I then adjust the SNMP and TR-069 settings on the WAN side I can retain admin privileges, effectively by locking Vodafone Es out. But then the telephone line is disabled and it is neither possible to make or receive telephone calls. My telephone is plugged into the back of the router.

I can see the SIP and VOIP configurations when I have admin privileges and they are obviously not correct. Can anyone advise me on what the correct configurations should be to make the telephone line work and VOIP. Many thanks. I have posted here rather than on a Spanish forum as locals in Spain tend to post back by just slagging Vodafone off rather than trying to address the topic of the post.

The only way I have been able to get the telephone line working again is to let Vodafone Es, back in, resetting the router and this losing admin privileges.

I would be most grateful for any help.

Many thanks.
