[Freeswitch-users] TLS and SRTP between 2 Freeswitch servers

[Peter P GMX]

Hello Brian,

I tried to set ;transport=tls on the sofia string and it showed me an 
invalid gateway

So I checked the gateway: server1 is not registered on server2
freeswitch at freeswitch> sofia status gateway freeswitch2
API CALL [sofia(status gateway freeswitch2)] output:
Invalid Gateway!

When I set the register-transport parameter back from tls to udp on 
server1 I get
freeswitch at freeswitch> sofia status gateway freeswitch2
API CALL [sofia(status gateway freeswitch2)] output:
=================================================================================================
Name freeswitch2
Scheme Digest
Realm xxx.xxx.xxx.56
Username 1007
Password yes
 From <sip:1007 at xxx.xxx.xxx.56;transport=udp>
Contact <sip:1007 at xxx.xxx.xxx.55;transport=udp>
To sip:1007 at xxx.xxx.xxx.56
Proxy sip:xxx.xxx.xxx.56
Context default
Expires 3600
Freq 3600
Ping 0
PingFreq 0
State REGED
Status UP
==============================
I ngrepped the traffic between server1 and server2 and could see that 
there was traffic on port 5060.

Switching back to TLS it didn't work again.
<param name="register-transport" value="tls"/>
I ngrepped the traffic between server1 and server2 on all ports and 
could see that there was absolutely no traffic between them.

So, as soon as I enter tls instead of upd, the traffic stops.
Any hint?

Best regards
Peter
