Ok, here are some snips of the call


Here is the initial invite that I receive from the client...

I forward this to my pstn gateway, and that is the 200 OK that I forward
back to the client.

gw -> openser -> client
<cut>
SIP/2.0 200 OK

And now the ACK for the 200ok
client-> openser
<cut>

The r-uri in the ack is wrong, it should be the contact from the 200ok,
and i can't route it to the rigth gateway.

So, there is some way that i can workaround this in openser?? Since is
very unlikely that the client will fix this issue.

Thanks
