Hi Geeks,
When I join a call to echo application with H264 as video codec there is no video sent back from FreeSWITCH while with VP8 it sends video.
I am using Linphone on iPhone 6 as SIP client
I am using FreeSWITCH Version 1.8.4+git~20181227T011058Z~749a6e108b~64bit (git 749a6e1 2018-12-27 01:10:58Z 64bit) on Debian Release 9.6 stretch.
mod_h26x is enabled and and it show it loaded,
freeswitch@Dev-Togee-media-fra-16> module_exists mod_h26x
true
it enabled as only video codec in var.xml,
<X-PRE-PROCESS cmd="set" data="global_codec_prefs=OPUS,PCMU,PCMA,H264"/>
<X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=OPUS,PCMU,PCMA,H264"/>
Linphone client send H264 in SDP offer,

but FreeSWITCH replies SDP without video ,

It is really strange behavior, I really appreciate any suggestion and help on it.
