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
