I have a sipgate SIP-account with money on it. Telephony works fine with Empathy. But how to configure Pidgin to support my SIP-account?
There is a ticket at pidgin's BTS for implementing SIP support: http://developer.pidgin.im/ticket/9754
The free bidirectional SIP2GTalk gateway service http://gtalk2voip.com does not work with pidgin's Jingle implementation too...
