[Asterisk-Users] SIP Link on Web Pages

[Barry Fawthrop]

Hi All   In Order to place a "call Me" button on a webpage which would you use ?   [A]  <a href="">Call Me</a>   or   [B]  <a mailto:"sip:[EMAIL PROTECTED]">Call Me</a>   Then what s/w is required on the users end to make the call so that it rings via an * server to a sip phone (ip phone) registered with the * server 123.123.123.123 ??   Thanks in advance Barry
