Hello All,

I have a couple of questions Regarding NatHelper & RTPproxy

1. Does NAThelper assist in NAT traversal when STUN cannot manage due

to Symmetric NAT.

Yes.

2. Does NAThelper provide any help when NOT used in conjunction with

RTPproxy.

for some scenarios yes.

3. Are there any SER.cfg settings that are suggested to get started

with NAThelper. (We are using grand stream devices in addition to a few ATA)

There is an example config file: sip_router/etc/nathelper.cfg in the CVS.

4. Am I correct in the assumption that if you use a RTPproxy - all the

real time voice traffic is passed through your network connection?

Yes, through the server on which the RTP proxy is running.
