Hello All, I am trying to enable IAX2 support for freeswitch. I successfully compiled and install PTLIB and OPAL. Also recompiled freeswitch with mod_opal successfully. Below is opal.conf. <configuration name="opal.conf" description="Opal Endpoints"> <settings> <param name="trace-level" value="25"/> <param name="context" value="default"/> <param name="dialplan" value="XML"/> <param name="dtmf-type" value="signal"/> <!-- string, signal, rfc2833, in-band --> <param name="jitter-size" value="40,100"/> <!-- Jitter buffer min/max size, milliseconds --> <param name="codec-prefs" value="PCMU,PCMA"/> <!-- list, and preferecnce order, of codecs --> <!-- <param name="disable-transcoding" value="true"/> --> <!-- do not transcode, use source channel codec only --> <param name="gk-address" value="*"/> <!-- empty to disable, "*" to search LAN --> <param name="gk-identifer" value=""/> <!-- optional name of gk --> <param name="gk-interface" value="<My Public IP>"/> <!-- optional listener interface name --> </settings> <listeners> <listener name="default"> <param name="h323-ip" value="<My Public IP>"/> <param name="h323-port" value="1720"/> </listener> </listeners> </configuration> On netstat for 4569 (IAX) port, below is the result udp 0 0 0.0.0.0:4569 0.0.0.0:* 16533/freeswitch I have one DIDWW DID configured with IAX2 protocol and routed to this server. When i am dialing this DID, i am getting calls on server which i checked in ngrep. However, there is no event on freeswitch. Just for your information, I configured mod_opal on both latest 1.2 and 1.4 version and found same result for both. Can anyone please help me what i need to do additonally to get IAX2 calls on freeswitch? Do i need to configure anything for IAX2 ? Is there any this i can test to check it is configured and working properly ? Thanks & Regards, Bharat Lalcheta
