Thanks Daniel. There is an update that i am having Secure signaling TLS. and in oder to deal with NAT issues , i had to put sip-force-contact=NDLB-tls-connectile-dysfunction to force rport and TLS issues. With this configuration chat does not work, BUT i just saw that* it works* when i remove the sip-force-contact parameter. :( Still for your observation, here is my profile Name 198.84.61.52 Domain Name N/A Alias Of internal Auto-NAT false DBName sofia_reg_internal Pres Hosts 198.84.61.52,198.84.61.52 Dialplan XML Context rokacomm Challenge Realm auto_from RTP-IP 198.84.61.52 SIP-IP 198.84.61.52 URL sip:mod_sofia@198.84.61.52:6000 BIND-URL sip:mod_sofia@198.84.61.52:6000 TLS-URL sip:mod_sofia@198.84.61.52:5061 TLS-BIND-URL sips:mod_sofia@198.84.61.52:5061;transport=tls HOLD-MUSIC local_stream://moh OUTBOUND-PROXY N/A CODECS IN G722,PCMU,PCMA,GSM,AMR,H263,H264,H263-1998,H263-2000 CODECS OUT G722,PCMU,PCMA,GSM,AMR,H263,H264,H263-1998,H263-2000 TEL-EVENT 101 DTMF-MODE rfc2833 CNG 13 SESSION-TO 0 MAX-DIALOG 0 NOMEDIA false LATE-NEG true PROXY-MEDIA false ZRTP-PASSTHRU true AGGRESSIVENAT false STUN-ENABLED true STUN-AUTO-DISABLE false CALLS-IN 20 FAILED-CALLS-IN 4 CALLS-OUT 10 FAILED-CALLS-OUT 4 REGISTRATIONS 3 and 9999 profile as: Call-ID: c6dfab23429f90be4a57c6c39a3fd3ef@0:0:0:0:0:0:0:0 User: 9999@198.84.61.52 Contact: "9999" <sip:9999@175.110.122.81:6000;transport=udp;registering_acc=198_84_61_52;fs_nat=yes> Agent: Jitsi1.0-build.3967Windows 7 Status: Registered(AUTO-NAT)(unknown) EXP(2013-03-08 15:07:12) EXPSECS(87) Host: rokacomdev1 IP: 175.110.122.81 Port: 6000 Auth-User: 9999 Auth-Realm: 198.84.61.52 MWI-Account: 9999@198.84.61.52 Anything else you need to see? But that is sure , the issue is due to sip_force_contact parameter in directory! -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/IM-messaging-on-FreeSwitch-tp7...
