> Hello guys,
> I'm sending you this e-mail because we have found two strange behaviours in the handling of ACK messages by openser 1.3.
> 
> The first one appears when an IP phone is requesting for a non-existing number.
> The proxy answers the phone with a "404 Not Found" which is normal.
> But, when the proxy receives the ACK from the phone it seems to ignore it and keeps on sending "404 Not found" for a couple of time.
> 
> The second one appears when an IP phone is cancelling a call.
> After the call is cancelled, then phone sends a "487 Terminated" message to the proxy.
> The OpenSER proxy answers by an ACK, which is normal but it seems the ACK is not recognized by the IP phone which keeps sending "487 Terminated" for a couple of time.
> 
> We done the testing with 2 different IP phones :
> 1) X-lite v3.0 build 34025
> 2) ACT P170S V.01.31
> 
> Please find the corresponding Wireshark capture files attached to this message.
