Sure Signal 3 dropping out?

[compressorman]

When on mobile suresignal working, if land line rings and is answered mobile phone cuts out, and sure signal goes to orange symbol & then resets once land line switches off.

I have opened all the necessary ports. I have bound MAC address to sure signal. Have done all the reset procedures.Nothing seems to work...its driving me crazy!!!!....it had been working fine next door.

I am with BT...they say all is fine....(as they would,I know!)  5.7download speed 0.64 upload speed.

Draytek Vigor 2820n modem router....Please help...spoke to your support,who seemed mystified to the problem,but reading on this forum, there seems to be a lot of similar issues???...Thanks for anything!!...I need it as Vodafone coverage for phones in this area are rubbish.

Hi compressorman,

You shouldn't need to change anything else.

Let us know if the issue persists over or if it appears to now be fixed.

Thanks,
