Dear all: I am confused with dingaling for several days. I hope someone could help me please. Below are my config steps: 1. Download “gnutls-2.9.9.exe” from “ http://josefsson.org/gnutls4win/” and install. 2. Build “libgnutls-26.lib” (refer to “ http://wiki.freeswitch.org/wiki/Ixemel_MSVS_project_example”). I have rebuilt the FreeSwitch. 3. Copy the TLS dlls to “C:\FreeSWITCH\Debug”. 4. Set the conf in “\conf\jingle_profiles\client.xml” (refer to “ http://wiki.freeswitch.org/wiki/Mod_dingaling#TLS” and the letter “[Freeswitch-users] Problems making a receiveing calls with mod_jingling” ). 5. Start FreeSwitch. Below are my config in step 3: <include> <profile type="client"> <param name="name" value="thisjoy"/> <param name="login" value="account@gmail.com/gtalk"/> <param name="password" value="pwd"/> <param name="dialplan" value="XML"/> <param name="context" value="public"/> <param name="message" value="Jingle all the way"/> <param name="rtp-ip" value="$${bind_server_ip}"/> <param name="ext-rtp-ip" value="$${external_rtp_ip}"/> <param name="auto-login" value="true"/> <param name="sasl" value="plain"/> <param name="server" value="talk.google.com"/> <param name="tls" value="true"/> <param name="use-rtp-timer" value="true"/> <param name="exten" value="888"/> <param name="vad" value="both"/> <param name="candidate-acl" value="wan.auto"/> <param name="local-network-acl" value="localnet.auto"/> </profile> </include> I input the command “dingaling status” and found the account was “UNCONNECTED”. Besides, I saw a message in “freeswitch.log”, it is: I. 2010-10-28 18:46:56.468750 [DEBUG] libdingaling.c:1237 TLS NOT SUPPORTED IN THIS BUILD! II. 2010-10-28 18:47:16.453125 [DEBUG] libdingaling.c:1607 io error 2 7 retry in 20 second(s) My OS is Windows XP and the FreeSwitch is 1.0.head. Thank you for helping. Sincerely yours, Thisjoy.
