[Freeswitch-users] Call UDP -> TLS

[Chusov Alexsander]

     Hello all,

I'm trying to deploy FreeSWITCH as a back-end for Opensips ( 
http://wiki.freeswitch.org/wiki/Opensips ). TLS -> Opensips -> UDP -> 
FreeSWITCH
TLS work fine end point is registered. But when call phone FreeSWITCH 
send invite use TLS instead of UDP.

Register exsample:
172.20.0.24 - opensips
172.20.0.22 - freeswitch
172.20.0.20 - phone

    REGISTER sip:172.20.0.22:5060 SIP/2.0

I'm not familiar with C + + to test made small changes I understand it's 
not right but it works
in src/mod/endpoints/mod_sofia/sofia_glue.c  1233, 1348  change

         } else if (!strncasecmp(str, "tls", 3)) {
                 return SOFIA_TRANSPORT_TCP_TLS;
         }

to
         } else if (!strncasecmp(str, "tls", 3)) {
                 return SOFIA_TRANSPORT_UDP;
         }



Can anyone tell how to configure FreeSWITCH for normal UDP->TLS TLS->UDP 
work. Or maybe I'm doing something wrong?


Sorry for my english
