This isn't exactly an SER issue but it was suggested that I ask here - iptel.org has an SRV record for a STUN: _stun._udp.iptel.org. 86400 IN SRV 0 0 3478 sip.iptel.org. But that server doesn't seem to be responding to STUN requests. Does anybody know if it should be working? Or is working for them? Thanks. Dennis
