[Asterisk-Users] SER is a better NAT solution?

[Kuniyoshi Murata]

Hi, 

I'm now setting up a VoIP conference room using Asterisk. 

All the clients are SIP phone (to be exact, Xlite), number of clients that should be registered are around 50 and concurrent users are maybe 15 clients at most. 

So, basically I think I can handle the situation only with Asterisk.
I'm wondering however, most of my clients are behind NAT of home router and using SER together with Asterisk sounds better solution. 

Is there significant difference between SER and Asterisk, for handling SIP phones behind NAT?
