[OpenSIPS-Users] Wierd OS ACK to private IP

[David Villasmil]

Thanks for answering,

     Yes, I thought so. Thing is I can't do anything with the caller device,
it is an eyebam. I believe this has something to do with ALG. The only
problem on the whole sip exchange is this ACK... is there no way to modify
that on the server? Also, the IP the UAC puts on the ACK is ITS OWN ip..
VERY wierd. Can we work around that somehow?


Thanks a lot

David
