Bug - LUA session:recordFile when using video phones
by Shaun Stokes 02 Oct '17

02 Oct '17

Hi All, FreeSWITCH version 1.6.19 We are using LUA “session:recordFile” to record greetings which works perfectly on non-video devices, however video phones (such as Polycom VVX500\VVX600, Yealink T49G etc) are not supported unless video is disabled on the device thus preventing it from attempting to negotiate video in the SDP message. We have H264 enabled in FS gobal_codec_prefs, disabling H264 also resolves the problem. From the point we begin the recording there is a 10 second delay before the recording starts on video devices, recording starts after the error “Unable to establish inbound video stream” occurs. 2017-09-28 13:01:39.885386 [NOTICE] switch_core_io.c:1202 Activating write resampler 2017-09-28 13:01:39.985376 [DEBUG] switch_cpp.cpp:895 getDigits dtmf_buf: 2017-09-28 13:01:49.985371 [ERR] switch_ivr_play_say.c:496 Unable to establish inbound video stream 2017-09-28 13:01:49.985371 [DEBUG] switch_ivr_play_say.c:560 Raw Codec Activated, ready to waste resources! 2017-09-28 13:01:49.985371 [DEBUG] switch_ivr_play_say.c:674 Raw Codec Activated We’ve tried to work around the issue by adding this to our dialplan before the call is answered but the same issue occurs: <action application="export" data=" absolute_codec_string=PCMA,PCMU"/> <action application="export" data="codec_string=PCMA,PCMU"/> Looks like this is a known issue: https://groups.google.com/forum/#!topic/2600hz-users/61XyiXya5Ik https://freeswitch.org/jira/si/jira.issueviews:issue-html/FS-9632/FS-9632.h… The JIRA “FS-9632” was marked as resolved but doesn’t appear to apply to LUA when using “session:recordFile”. https://freeswitch.org/jira/browse/FS-9632 Perhaps we’ve missed something, does anyone have any ideas?

How to overwrite Q850 errors code in freeswitch?
by Raviram Chandran 01 Oct '17

01 Oct '17

Since we have a errors code in PSTN call (IP -PSTN call) which we wanton our telephony server to pass those errors code directly to mobile apps. When subscriber's balance is lower than some predefined value during call setup, Warning header with SIP 180/183 response for low balance alert goes to calling Party (mobile client) and the call continues. If heart-beat with calling dialog fails or maximum time limit for the call is reached, Warning header with BYE message goes to calling party (mobile client) and the call is dropped. Other than this, following failure scenarios may hit during a call 1. Authentication failed 2. Account temporarily deactivated 3. Zero or inadequate balance while making call 4. Account already in use by configured number of users 5. Rate not defined 6. Called destination blacklisted 7. Any other application failure For all such failure scenarios, IN will send 408 SIP responses to client. This response will contain a Warning header specifying cause of failure and appropriate text message (configurable at IN). Format of Warning Header is as follows Warning: Cause_Code APP_Name "Error Text", e.g., Presently error codes are configured at network provider end which we need to pass from our telephony server to mobile apps
