You are right: It should only be used as a last resort. > Fortunately, there is a practical solution for this issue: ICE > http://tools.ietf.org/html/draft-ietf-mmusic-ice-19 > > You still need a SIP proxy, but ICE is "intelligent" enough to check if > you really need it, thus this will only use the bandwidth if necessary. Ekiga is already able to detect a symmetric NAT, in this case a default proxy should be used. > ICE is planned to be implemented in Ekiga.

A free and standard compliant VOIP solution which works out of the box for all users is one of the things painfully missing on the Linux Desktop.
