Hi, I'm trying to secure (SRTP) the b-leg for a call coming in via pstn (pri/freetdm). For this I'm setting sip_secure_media and also trying sdp_secure_savp_only, but it seems freeswitch does not offer SAVP to my client (which in turn will refuse). SIP-to-SIP this works fine. Here the the portion of the log where I would have expected to see SAVP in the sdp: EXECUTE FreeTDM/1:5/21 bridge(sofia/external5090/21%10.1.1.12) 2013-06-28 09:20:10.800816 [DEBUG] switch_channel.c:1176 FreeTDM/1:5/21 EXPORTING[export_vars] [sip_secure_media]=[true] to event 2013-06-28 09:20:10.800816 [DEBUG] switch_channel.c:1176 FreeTDM/1:5/21 EXPORTING[export_vars] [dialed_extension]=[21] to event 2013-06-28 09:20:10.800816 [DEBUG] switch_channel.c:1176 FreeTDM/1:5/21 EXPORTING[export_vars] [sip_secure_media]=[true] to event 2013-06-28 09:20:10.800816 [DEBUG] switch_channel.c:1176 FreeTDM/1:5/21 EXPORTING[export_vars] [sdp_secure_savp_only]=[true] to event 2013-06-28 09:20:10.800816 [DEBUG] switch_ivr_originate.c:2050 Parsing global variables 2013-06-28 09:20:10.800816 [NOTICE] switch_channel.c:1030 New Channel sofia/external5090/21 [2b0bff7e-dfc3-11e2-b111-c96542f7174a] 2013-06-28 09:20:10.800816 [DEBUG] mod_sofia.c:4420 (sofia/external5090/21) State Change CS_NEW -> CS_INIT 2013-06-28 09:20:10.800816 [DEBUG] switch_core_session.c:1341 Send signal sofia/external5090/21 [BREAK] 2013-06-28 09:20:10.800816 [DEBUG] switch_core_state_machine.c:416 (sofia/external5090/21) Running State Change CS_INIT 2013-06-28 09:20:10.800816 [DEBUG] switch_core_state_machine.c:455 (sofia/external5090/21) State INIT 2013-06-28 09:20:10.800816 [DEBUG] mod_sofia.c:87 sofia/external5090/21 SOFIA INIT 2013-06-28 09:20:10.800816 [DEBUG] sofia_glue.c:1191 sip:21@client.ip.is.secret:49915;rinstance=e177370cb4131e9f;transport=tls Setting proxy route to sofia/external5090/21 2013-06-28 09:20:10.800816 [DEBUG] sofia_glue.c:1220 Local SDP: v=0 o=FreeSWITCH 1372384350 1372384351 IN IP4 my.ip.is.secret s=FreeSWITCH c=IN IP4 my.ip.is.secret t=0 0 m=audio 19660 RTP/AVP 8 3 101 13 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=ptime:20 a=sendrecv m=video 20590 RTP/AVP 34 98 a=rtpmap:34 H263/90000 a=rtpmap:98 H264/90000 Any help with this would be greatly appreciated.
