[Freeswitch-users] send_silence_when_idle=10000 Breaks inherit_codec?

Hello All, We want to configure Freeswitch with the following tags, but there are undesired side-effects. In conf/vars.xml: <X-PRE-PROCESS cmd="set" data="send_silence_when_idle=10000"/> In conf/sip_profiles/internal.xml: <param name="inbound-late-negotiation" value="true"/> In conf/dialplan/default.xml: <param name="inherit_codec" value="true"/> The problem is that setting send_silence_when_idle in vars.xml (above) causes ringback_data to get set in switch_ivr_originate.c (around line 2070) which causes 183 Session Progress w/SDP which prevents inherit_codec in internal.xml (above) to work as expected. This looks like a bug? Thanks, Jerry
