Hi Nikolay Kondratyev, I read your reply to opal to sip problem issue at http://lists.freeswitch.org/pipermail/freeswitch-users/2010-December/066082.... You said you use FS with mod_h323 ad sip<->h.323 gateway successfully. This what I want and I am hoping your help. Here is my issue: My video call is failing from X-Lite softphone(SIP protocol) to Ekiga softphone(h323 protocol). Ekiga softphone is answering the call but there is NO VIDEO transfer only audio transfer. My X-Lite softphone is at 192.168.9.165 and Ekiga softphone is at 192.168.8.27. Freeswitch server ip : 192.168.8.41 I have made changes in Local_Extension of default.xml such that if any registered extension has been dialed ,call will be forwarded to softphones at 192.168.8.27. <extension name="Local_Extension"> <condition field="destination_number" expression="^(\d{4})$"> <action application="export" data="dialed_extension=$1"/> <action application="set" data="effective_caller_id_number=${dialed_extension}"/> <action application="set" data="PEER_IP=192.168.8.103"/> <action application="set" data="call_timeout=30"/> <action application="set" data="hangup_after_bridge=true"/> <action application="set" data="proxy_media=true"/> <action application="bridge" data="h323/$1@${PEER_IP}"/> </condition> </extension>. Here is my freeswitch console log for video call from X-Lite softphone(SIP protocol) to Ekiga softphone(h323 protocol): 2013-04-29 02:34:00.220733 [NOTICE] switch_channel.c:978 New Channel sofia/internal/1100@192.168.8.41 [c7188b62-81ca-4225-9c8e-ccdb32e97af2] 2013-04-29 02:34:00.260553 [INFO] mod_dialplan_xml.c:557 Processing navnath <1100>->1101 in context default 2013-04-29 02:34:00.479931 [NOTICE] switch_channel.c:978 New Channel h323/1101@192.168.8.27 [cf6f458c-c443-40ea-ab5a-6660853b5df8] 2013-04-29 02:34:00.479931 [WARNING] switch_core_session.c:635 h323/1101@192.168.8.27 does not support the proxy feature, disabling. 2013-04-29 02:34:00.479931 [WARNING] switch_core_session.c:648 h323/1101@192.168.8.27 does not support the proxy feature, disabling. 2013-04-29 02:34:00.479931 [NOTICE] mod_h323.cpp:856 capability 'G.711-ALaw-64k' format 'PCMA' 8 2013-04-29 02:34:00.479931 [NOTICE] mod_h323.cpp:856 capability 'G.711-uLaw-64k' format 'PCMU' 0 2013-04-29 02:34:00.479931 [NOTICE] mod_h323.cpp:856 capability 'GSM-06.10' format 'GSM' 3 2013-04-29 02:34:00.479931 [NOTICE] mod_h323.cpp:856 capability 'G.729A/B' format 'G729' 18 2013-04-29 02:34:00.479931 [NOTICE] mod_h323.cpp:856 capability 'G.729A' format 'G729' 18 2013-04-29 02:34:00.479931 [NOTICE] mod_h323.cpp:856 capability 'G.729B' format 'G729b' 18 2013-04-29 02:34:00.479931 [NOTICE] mod_h323.cpp:856 capability 'G.729' format 'G729' 18 (.navn 61 74 68 00 6c 05 81 31 31 30 31 70 05 81 31 31 ath.l..1101p..11 30 31 7e 03 06 05 20 b8 06 00 08 91 4a 00 06 01 01~... .....J... 01 80 44 34 28 c0 09 00 00 3d 14 46 72 65 65 53 ..D4(....=.FreeS 57 49 54 4 2013-04-29 02:34:00.600359 [NOTICE] mod_h323.cpp:1147 Ring-Ready h323/1101@192.168.8.27! 2013-04-29 02:34:00.600359 [INFO] h323ep.cxx:3048 Received alerting PDU.
