Thx Alex Finally I clarified question for myself UAC not ignores Route in case of direct connection to provider It sends to needed ip:port on the transport:network layers
So provider wrong in case that avaits ACK at the different port than Route.
THx all .For now all clear.

Jut in update In kamailio case all goes well Kamailio sets to UAC Record-Route in the 200 reply and then UAC sends ACK via Route sent...
I totally confised... In both examples from my provider 200 contains Route set but in case of kamailio UAC uses route and in case of provider it uses Contact...
both Route heanders contains "lr"
Provider based Route header jsut contains only *sip:ip:port;lr *when my testing kamaili regitrar contains *sip:ip:port;lr,ftag=fromtaghere*

That was my point also... But they sent me lint to rfc3261 12.1.2 and that confused me
So just for resume:
So am I right if I say that in case If provider receives INVITE with Record-Route from my side (myProxy) Provider should care about it's own Record-Route and it should have
uri
where myProxy should sent ACK to instead of using Contact in thi case
In case direct conntect UAC -> Provider I still need to use Contact
field
as URI to send ACK to that explained on the 12.1.2 of rfc3261?
If the provider sent you a Record-Route of their own in addition to any that you have placed there, your UAC must still follow it when contacting them for in-dialog requests.
