[asterisk-users] Asterisk 11, SIP. OK to BYE goes to wrong ip/port combination

[Alex Zarubin]

Hi all,

I've read several discussions about asterisk adding 'received' parameter to the top Via header.

In our case asterisk (release 11.4) gets BYE from sip proxy (with BYE top via header containing proxy ip address and port) but added 'received' parameter contains ip address from a 2nd Via (or from "From') and OK gets lost.

I'm just trying to adjust sip configuration that used to work for simple call scenarios (in 1.4, for example) for Asterisk 11.
Your input is appreciated.

Thank you.

In sip.conf

[general]
nat = no
outboundproxy=PROXYipaddress:PROXYport

[CARRIER]
type=peer
host=CARRIERipaddress
port=CARRIERport
canreinvite=no

Outbound call from asterisk is established normally via outbound proxy. BYE coming from the CARRIER

Asterisk adds received=CARRIERipaddress (taken either from 2nd Via or from 'From') and sends OK to CARRIERipaddress:PROXYport.
This OK goes nowhere, carrier re-sends BYE several times...
