Re: [Serusers] Asterisk SER NAT issue

Hi Thorsten, both platform SER and Asterisk has the capability to deal with NAT without any problem. If you decide to use Asterisk only to be in charge about the NAT issue so you don't have to configure anything at SER but if you want that both of them share the job, so you have to configure nathelper and rtpproxy/mediaproxy at SER. Ragards.

Do I need the nathelper?
