And try to repeat this

transport

I try to configure a transport for each interface . This is very big mistake. This is the root of all the problem. This is not work normaly.
Then I try to configure one transport for all interfaces, all started working fine.
Below is an example of a working config.

[transport-all-udp]
type=transport
protocol=udp
bind=0.0.0.0:5060
local_net=192.168.129.0/24 ; Network on 1-st network card
local_net=192.168.64.0/24  ; Network on 1-st network card
local_net=192.168.77.0/24  ; Network on 1-st network card 
local_net=10.16.2.0/30 ; Network on 2-st network card  (Provider №1)
local_net=10.26.2.0/30  ; Network on 3-st network card (Provider №2)
local_net=172.27.240.192/30  ; Network on 2-st network card  (Provider №1)
allow_reload=yes
symmetric_transport=yes
tos=cs3
cos=3

Below is an example of a NON-WORKING config

; Transport for local clients
