I was able to successfully install SER and I can make calls. But I have two problems with it, they are
1) Even unregistered Users are able to call out.
2) We have few computers connected via LAN and we are connected to a router. We have a UNIX box somewhere else on which we installed SER. My problem is from computers which have indiviual IP are able to make and receive calls but in my internal network we are having one way problems or sometimes we are unable to make or recieve calls.
I am attaching my ser.cfg, please check it and help me to solve my problems.
Thanks, Manoj.

Hello,
My setup is for an INVITE session is:
UAC ----> SER -----> UAS
I am using SER is a stateful forwarder (using t_relay). I find that when my UAS sends a "200 OK" to my UAC (via SER), SER does not send an ACK to my UAS. The 200 message is forwarded correctly to my UAC, but my UAC is taking quite some time to reply. Therefore, there is timeout, and my UAS is re-sending the 200 messages to SER (and SER just forward them on to my UAC).
My question is, is this correct behaviour? Or is SER supposed to ACK immediately a 200 message, before forwarding it to my UAC?
Thanks for any pointers!

Hello.
Just an update on my previous post.
After reading section 16 in RFC3261, it looks like SER is not supposed to send an ACK to a 2xx response (in an INVITE dialog), since this ACK is supposed to be generated by UAC core. A proxy (like SER) would not implement UAC core functionality, even if it is in stateful mode.
So, it means that SER is behaving 'correctly' as described below.
If anyone has noted otherwise, please share with me.
Thanks!
