[SR-Users] Fwd: Re: http://kb.asipto.com/kamailio:skype-like-service-in-less-than-one-hour

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I've worked out what's going wrong and I fear there is a mistake in your config at: http://kb.asipto.com/kamailio:skype-like-service-in-less-than-one-hour inter-domain calls are going in plain text over UDP. I can see the invites at the reciving end doing a packet capture using tcpdump. My firewall blocks these thus explaining why nothing was seen in the kamailio log at that end. tcpdump -vvv -i eth0 src 46.43.48.253 and udp and port 5060 >debug.txt How do I make all inter-domain traffic only TLS? I've ensured that there are just valid TLS SRV records at both ends: host -t SRV _sips._tcp.unspeak.im _sips._tcp.unspeak.im has SRV record 0 0 5061 unspeak.im. host -t SRV _sips._tcp.atoll.dmcip.com _sips._tcp.atoll.dmcip.com has SRV record 0 10 5061 atoll.dmcip.com. Many thanks for all your help so far.

There is nothing in the called server's (unspeak.im) logs from the call. johnc(a)atoll.dmcip.com ----Call---> gnuday(a)unspeak.im The call gets as far as "SIP 100 trying". Both servers have only port 5061 TCP open on the firewall to only allow TLS. Any help would be greatly appreciated. Many thanks. Regards, John
