I couldn't find anything in the tech specs for these phones on this.
I'd like to know if a land line can be plugged directly into the phone. VOIP via my Samsung Officeserve Softphone has proven to be spotty even with a very stable Internet connection so it would be nice to tie it all together with a VOIP phone and land line all-in-one. I just don't know how or why one of these phones would be more reliable than VOIP via the current softphone or the Google Chat interface.
Thank you,
