Comment (by chemistrydioxide):

 I just noticed that Sipgate is advertising their STUN server via DNS. This
 means that i can use it without needing to change Pidgin.
 {{{
 chemistrydioxide at localhost:~$ host -t SRV _stun._udp.sipgate.de
 _stun._udp.sipgate.de has SRV record 0 0 10000 stun.sipgate.net.
 _stun._udp.sipgate.de has SRV record 10 0 3478 stun.sipgate.net.
 _stun._udp.sipgate.de has SRV record 10 0 10000 stun.sipgate.net.
