I switched to naked broadband some time ago. I thought using a voip service would suit my needs but I am having a terrible time. My laptop sound card died (I was using 2Talk Softphone) so I purchased a USB Sound card. Trouble is whenever I talk to anyone people complain it is a bad line even though on my end people sound clear. Would something like Grandstream Handytone be any good. I am not sure whether to get an ordinary phone line again or stick it out with this. Can you receive quality phone calls and what types of equipment do you use to combat issues. It would be much easier to stay on the plan I am on. Thanks for your help in advance.

UPDATE: Have just bought  Linksys PAP2T ATA
