Hi Tito,

It looks like you moved faster than me :) . Typically, when you have routing problems like missing ACk, in 90% is about a contact or Record-Route header which got broken, preventing proper in-dialog routing.

Bogdan,


I found the issue. It seems that fix_nated_contact was the culprit. I wasn't for nat in reply route so when the call was coming in I was trying to fix the nated contact which wasn't nated. This was already done in the source/remote proxy. I found this to be the source of other issues where acks were being sent with the proxy address rather than what sent in the 200 ok contact. THank you for looking into it.


Thanks,
Tito

    Does anyone in the group have any ideas on this issue? this is
    puts a crux on my distributed HA/load balanced design. Since I
    can't fork calls to proxies in which other users may  reside on.

        Group,


        I am having issues with opensips version: opensips 2.2-dev
        (x86_64/linux)
        git revision: 1e998bb
        forwarding an ack post 200 ok sourcing from a remote opensips
        proxy is not being sent to the UAC to initiate the dialogue.
        Not sure what has changed from 1.11 as far as this sort of
        processing but now the ack is being dropped. I have taken a
        trace and logs from the side that wont transmit the ack.

        https://www.dropbox.com/s/kznqi18h7rokhvj/2.2issues.tar?dl=0

        I have also included the opensips.cfg in case there are any
        questions regarding the config.


        Thanks,
        Tito
