[Asterisk-Users] STUN vs NAT Helper

[Waldo Rubinstein]

I'm wondering if anyone can recommend one over the other. I'm mostly  
interested in running open source solutions, so I would prefer if  
your recommendations are within the open source arena.

Basically, I contemplated the idea of using SER as a NAT Helper and  
possibly as a SIP server for a portion of our user base. We prefer to  
have Asterisk in the mix because of the additional wealth of features  
it can add to the SIP services (e.g. voicemail, ivr, call queueing,  
etc).

All of our clients are behind NATs, mainly basic NATs such as linksys  
routers behind DSL modems.

I read on the wiki that STUN is not readily supported by most  
clients, so I don't know if its worth the effort or if we should just  
concentrate on getting SER working with Asterisk.

Any ideas or suggestions?

Thanks,
Waldo
