Could anyone help me with configuring any Linux softphones for use with SIP betamax services? In Windows, I was using 12voip.com to make calls and send SMS. However I have failed to correctly configure Linphone and Ekiga so far. All the instructions in Internet seem to relate to old versions of Ekiga. I have also tried the original 12voip (Betamax) client with Wine, it installs, runs but fails to log in. Thanks, guys!
@Administrators: Please, replace the 'software-recommendation' with some reasonable tags (e.g. betamax, sip, softphone) to this question. I cannot create tags yet.
