Hi, Regarding ICE strans in the PJNATH library. I'm curious as to whether I've misunderstood the 'default candidate' selection process currently in ice_strans.c. At the moment, the default seems to be set while possibly still pending full initialisation (e.g., if I set stun-srv, the default_cand is set to indicate that this is the default candidate while STUN is still pending a response; if a response never arrives, then the default candidate addr is 0.0.0.0, and things may then fall over on attempting a call). Would it make more sense to only set the default candidate to the HOST address on init, and then subsequently set the default candidate inside the stun_on_status() and turn_on_status() functions, if a more appropriate default becomes available? As I understand draft-ietf-mmusic-ice-19, the default should be the most likely candidate to allow a peer to successfully transmit data inbound (so, generally, relay == most likely, host == least likely, if we assume the host has nominated a relay for good reason), which is somewhat at odds with the preferred choice of (host == best, relay == worst). But surely if a STUN bind hasn't succeeded, and/or a TURN relay hasn't been allocated, then the -only- default which can be set is the host. No? Cheers, -S.
