Can not transfer h264 Video throw Asterisk 13.11.2 PJSIP.

Detailes below
Thank you in advance
Ilya
topology:
two Video sources
Aster UA (SipPhone on Win)
GOOD 192.168.0.220---->
PT=97
192.168.0.200 -----> 192.168.0.3
/
BAD 192.168.0.210—>
PT=98
!!! Call from source A is ok, but from B No video. !!!
The only difference I found is different Payoad Types (PT) of sources (mentioned above).
(sipsak and 127.0.0.1 loopback below is a sipproxy)
